But if boethius was, as @Outlander said, "just trying to look out for the best interest of Jamal, and as a result, all of us," you have to wonder why he responded to every correction with an evasion such as "Well the main point is that..." — Jamal
There's zero evasion, the idea you could start a business and cannot ever be summoned to court is absurd, for any business. Moreso for a business that does anything remotely controversial in addition to hurting specific people's feelings (which, at least from my perspective, some banned members seem to have had their feelings hurt).
Risk analysis starts with considering extreme scenarios and then working your way down to the mundane.
It will be your business. If you don't want believe anything extreme could possibly happen, such as some government official in the UK reading something published/hosted by your business and being like "we need to put an end to this," then ok don't believe that could possibly happen.
The reason I propose that as a risk worth considering is because there's a pathway available to you at the moment that would reduce all categories of speech-litigation risk, from the smallest to the most extreme, which is incorporate in a place with far more clear and secure freedom of speech laws. UK may still take issue, but they can't force a foreign business to do something in a foreign country without that also being the law in that foreign country (they also know foreign countries don't like that, same as no UK judge wants to be told what to do by some foreign judge according to laws that don't exist in the UK, say sharia law, so the reticence to even try to compel a foreign company to do something is extremely high).
However, if you're response is "that's fantasy, no government official has ever taken issue with things people say online and then gone about abusing power to suppress that speech or as retaliation," well then ok, sure, but there's still all the other categories of litigation risk.
As I say, make your own risk scenarios and assign your own likelihood and impact numbers to them.
Some scenarios (disgruntled ex-forum client of your forum business) I'm not saying are existential, just a pain in the ass that you may need to deal with and other strategies available avoid creating service-client legal relationships.
The purpose of considering this category of risk is that you may need to deal with such a scenario that consumes a lot of your time, all the money, and a lot more, you've brought in through the service equivalent of donations, and completely erases all the benefits and peace of mind you thought the business would create for you. Now if you sit down and think about this scenario and conclude the risk of this happening is 20% ... ok, is that a risk you're willing to take?
And so on for other risks, all the scenarios I propose have some likelihood of actually happening.
As with all risk analysis, there is a threshold below which the additional risk is just added noise to your daily risk of being just being alive; just another of many improbable disasters that could befall you at any moment from being struck by lightening to being in a plane crash. Risk is non-actionable when it approaches this "improbable disaster noise".
Risk that requires further analysis is anything above this "background risk noise".
Doesn't mean anything has to be done about the risk but only further analysis can provide some reason to do nothing. To take base jumping, once the weather is such that there is a "freak gust" risk that could be lethal, maybe our base jumper is still going to jump but it obviously depends on "how likely": 1 in a 1000 is way higher than the otherwise risk of death that day, but perhaps still far below the base jumpers risk tolerance, but let's say some numbers guy comes up with 1 in 10 ... obviously a different situation and anyone who jumps would be considered to have a death wish, playing Russian roulette for all intents and purposes.
In terms of dealing with the risk, even super mundane legal harassment by an ex-member that has zero merit and can't possibly win but a judge is willing to give them their day in court to hold you accountable, you still have to show up in court and deconstruct even spurious arguments.
There's a whole spectrum of risk, lot's of risk categories, the "go-no-go" decision should be based on some rational evaluation of all the risks and summing them over a reasonable period of time before a choice to renew, handoff or abandon naturally re-emerges, say 5 years, and that total risk below your risk tolerance.
Now, exactly what number in terms of likelihood and impact will be somewhat subjective. Take our base jumpers, they may agree there's wind, may agree gusts to happen, but one may "feel" the weather is simply calm enough that a freak gust would be 1 in a million, so jumps, and another feel it's more like 1 in a hundred and so doesn't jump.
The rational framework for making the decision is nevertheless the same for each jumper.
So in your case, you should make a spreadsheet with the different categories of litigation and compliance risk, and punch in numbers of likelihood over 5 years and then impact (basically money required to deal with the eventuality). The sum of all these values will be some expected value of the decision.
From a business planning perspective, what really bothers me is that no actual benefits have been described. You could change technology, comply with the laws, without making a business and creating any of these client-service litigation risks.
So, the expected value in this case is always negative. Normally, for a business, or then new business project, to be a good idea you go through this exercise about the risk and then go through the same exercise about the benefits. Analytical milestone 1 is the expected value of the benefits far outweighing the expected value of the risks.
To take our party management corporation for example, all the risks of what can befall wild party goers (and the impact on the bottom line) can be analyzed in the above way, but then also all the benefits of people paying for the party, networking with celebrities that absolutely need to be at your parties, legal consenting sexual opportunities as the party maestro everyone loves and so on.
However, if you go through all the costs and risks and the expected value of costs exceeds the expected value of the benefits, then the decision cannot be rational.
Analytical milestone 2 is then considering the stochastic nature of reality and that even if the expected risk-benefit is positive there is still the possibility of catastrophic failure, and that's where the risk tolerance comes in.
Analytical milestone 3 is then considering the ways to lower the risks even further and amplify the benefits.
