to punishing ?
Why should players be punished in an illegal way for a legal behaviour , which you donĀ“t like ?
In any system, if people are acting in an undesirable way, they need to be punished in order for that behavior to stop. When one has the recourse of a functioning legal system, then this is a reasonable way to punish them. But if the legal system favors those in power (for example if it caters to the needs of the wealthy in a society where wealth is the predominant means to power), then the only method of punishment available is "illegal".
To say it in another way in a more positive light, behavior is only illegal when the consensus of the society says that it is. If the society agrees that something is no longer illegal (or that something that is usually illegal ought to be allowed in a circumstance), its punishment is rarely enforced. If someone (particularly someone in power) is engaging in a legal action which is detrimental to society, it is the moral imperative of the populace to communicate in a way that will allow them to coerce that person to stop their behavior, regardless of whether that communication is considere to be "conspiracy".
If there is some legal method available, i'm all ears, but -rep was the only thing that sprang to mind. Honestly thats pretty much what happens in the real world. Like there is no law (that i know of) about showering, but if someone walks around stinky all day they are gonna get shamed into bathing because of their bad reputation.
As far as people who don't have forum accounts, I hadn't considered that someone who had invested all the time in getting 100000 points or whatever you need wouldn't have a forum account, but i suppose its possible.
