Am I missing something?

Is this some sort of advertising thing? Noticed it in a couple different threads and thought i was missing some inside joke. the account was made in the past week.

Thanks for pointing it out.

Looks like someone made legit posts, let them stick until the thread went quiet and them went back in and edited them to include the spam links.

Spammers are clever.
