Just wonderin' why I got banned + questions.

[rugerty1OO]

My account name is "Rugerty100" and I got the ban message "Outside links. Do not be sneaky about it." I do not dispute this ban, just wondering from which place it came from, because I don't remember being sneaky about anything. And question: Are you allowed to create an alternate account to use during 3 day bans? "- No ban evasion on an alternate account for serious bans. (Permanent Ban)" I don't think this is a serious ban?
Second Question: Are we allowed to send outside links in private messages?

EDIT: I realized there was a quote in my email. Anyways, I'm wondering why I was banned and not @Arii, even though he's the one that sent me the link in the first place....(Not asking him to get banned.)
