First off, you were muted for being offensive, which is actually in the screenshots you provided.  Secondly, scam accusations are cause for mutes actually, because a bunch of senseless scam accusations with no proof do not belong in the public chat.  People getting scammed is usually their own fault for engaging in trades or loans which are against the rules to begin with.

In addition, you caps spam in chat a lot too.  I could have muted you for a lot longer, but I didn't.
