Update: bans from modlog in purple.

For a few days my giveaway-thread didn't have much Alt-spam. Today they returned in full force. They don't follow the rules of the giveaway, they cheat by trying to join with many accounts, and they basically just spam the thread.
They usually post in a row, and if you check their post history they do the same in other giveaways. All accounts use all the same giveaways only.
On the last page 6 out of 8 posts are from alt spammers:

On the last page, user: karekas33 (Autoban user: N/A in topic #0 by member #863399) follows exactly the same post pattern, but he did actually do as the giveaway instructs. He could be the Genesis Alt ^{(TM Timelord)}. Going through his post history, I was surprised to see he typed a few real messages. So I entered them into Google, big surprise, it's copy/pasting:

I like the irreversible nature of transactions with bitcoin, knowing that once I receive btc in my wallet, there's no one on the other end who can take it back (but of course this can be problematic from the reverse perspective).

@Lauda: Is there anything to do about the alt spammers? Can they be nuked, or is this not enough? If they can be nuked, I can go through the hassle of making a much longer list. If not, I'll save myself the time.
I'll leave karekas33 here, as he's my suspected Genesis alt, and send it by pm to The Pharmacist. Judging by his Trust history he'll go after him Tongue
