People really are desperate enough for just 1LTC... So far we've added blacklisting (efnet rbl, spamhaus, a few others), with a personal blacklist as-well, a sliding adscaptcha, and since it uses a round system, they also need at least 20 addresses and different IP's in the round before they can even get a pay out.
Oh, and recently the actual wallet system got nuked with over 2000 new wallets, partly due to googlebot, but also some other asshole spamming it to hell, so I've added another captcha there.
This is what the ShortBusCoin folk do in their spare time since microRASH hasn't launched yet!! LOL
