So, what if a member have a second account but did not publicly announce on the forum that the account belongs to them and they also do not cheat with the account and don't have intentions to cheat with the account but for their own best reasons, they don't just want to publicly announce it, what would be the consequences if it's is noticed?
Consequences.... Well if you ask me the forum isn't like some sort of school system where you get punished if you do wrong. However that doesn't mean that cheating will be overlooked all the time. Basically if you scam or have made use of them to cheat in any way in the past which has a high chance of occuring then you will likely get tagged.
Nevertheless I've seen a couple of cases too where users got tagged for having ALTs and it's always because they hid it so long and most times had both accounts in different signature campaigns or worse both.
