Maybe wrong, maybe right?

There was someone that joined CS today... And they said that they joined because they're friend told them it was a good game? All they adopted was the advent tree; no monthly pets, no groups, just the advent tree. They haven't been on after they just adopted that. Not too sure... But I think someone is cheating...
EDIT:
She has 1 post, no avatar! If a friend introduced you to CS, I am pretty sure they would show you where to get the monthly pets too... I don't know anymore now!

If you are suspicious then you can always use the 'report this player to the mods' link on their profile page. But of course, some people really do join on the 18th and decide the site isn't for them, or perhaps it was a friend introduced by someone else.

If accounts join just for the 18th though, then they won't actually be able to cheat and adopt more rereleases, as accounts which join close to the day are prevented from adopting - for that very reason.
