This is only partly true. It is true that having alternate accounts is not explicitly prohibited by the forum rules, but it may constitute a violation of established community norms as well as local campaign rules set by campaign managers. Of course, there are legitimate reasons for having an alternate account, but there are numerous situations in which using an alternate account is immoral, to say the least. For example, you are not allowed to use an alternate account for: evading a ban, bumping your own thread excessively, creating fake conversations between multiple accounts, participating in contests or bounty campaigns if prohibited by campaign rules, etc.
I'll summarise this to mean, giving others a chance.
Just as a reminder, the forum is a discussion platform and it's outrightly wrong for one to be discussing with one's self as the case might be for alt account farmers, meriting themselves and other shifty behaviours as such. The cryptocurrency atmosphere operates largely on trust and being shifty like the Fox of cause not Foxpop apparently, lol... it give a wrong impression about you. Makes you degenerate, untrustworthy and only insane persons behaves tha way @OP.
My question now is, is it a violation of law for hunters to send token to one another? Even if the linking address has nothing to do with the forum like in their POA? Why are many being accused of alt accounts even without enrolling multiple accounts in one campaign?
What we now refer to as "Accusation of owning an alt" according to OP, especially when linked with a particular account is just a statement of fact. It's left of you to clarify if it's true or not by disproving the evidences against the accounts. Have you eve wondered what the case might be if an alt account owner just accepts the obvious?
If it happens to be true, you didn't deny the obvious and you haven't violated any rule, your surely going to be left alone with your alt. It only becomes an issue when certain forum rules have been violated such as, merit exchange, spamming etc.
In fact, sending tokens between wallet addresses isn't a violation. Your free to do that. I've seen some forum users transact coins between themselves and even get to rate themselves on the trust system. Your not by anyway restricted from transacting on the forum. Just ensure you go by the rules and the rules will keep you safe.
