likely sig spammers
They dont have sigs.
But its just a misunderstanding. People think that a casino is only for gambling, but many bitcoin casinos offer investment services as well.
Most bitcoin casinos work on a crowdfund model, whereas the bankroll is madeup of investors money, so the risk and both reward is shared between the house and the investors.
Fairly certain Exurban's was a genuine misunderstanding - sig spammers tend not to engage with other posters when called out or questioned.
Sig spammers don't necessarily have signatures. Posters need to "level up" before sig campaigns will accept them - a lot of the sig spam comes from new users trying to reach the point where they'll get paid for their spam. I've been following a particular type of sig spam (
"canned posts") - when I first raised it on meta most of these posts had sigs; since I posted I've been reporting these posts and they now tend not to have signatures (I don't know how ethical this is, but I've
not been reporting posts without sigs - I figure let them waste time levelling-up, and once they start posting with a sig - report their posts, and
wham.)
The list is disappointingly short - not a criticism of you, RealBitcoin, just a comment on the disappointing lack of innovation in the BTC community. ramesh770 mentioned starting their own site - obviously that wouldn't be investing with BTC, but entrepreneurs like this open up opportunities for the rest of us to invest with our BTC. BTC needs more innovators! I'd like to see more BTC derivatives available, but I secretly hope people will come up with entirely new ways to - safely - invest with BTC.
