Users create an account and make a post offering $17 to test their casino as we can see in the image:
Then they told you, to withdraw you only have to place a bet, your bet will win, and after that, they will ask you for a depo to verify your account and that way you will be able to withdraw.
And i know this because i get scammed by them some weeks ago, i think it worth the risk to lose 0.01 for the chance to withdraw 0.7btc... I lose that money and learn the lesson, but if the forum doesn't stop these fuckers lot of user will get scammed with this schema. So, be careful people because they will not stop creating accounts and spamming.
I'm not sure this is something new on the forum, but only this time it has a bit bigger proportions than before. Victims of such scams are usually inexperienced persons and probably 90% of them never even report that they are scamed. This time you fell into the trap, and it is easy to say now that you should know how old is this trick.
I can say it is much older then BTC, works on same scheme as Nigerian scam. To get promised prize you only need to deposit some money as proof of identity, and when you done that it is game over. Scamed users sometimes ask why they can not get their money and get scamed again because they are asked for one more deposit, because first one is stuck.
I agree with you that we should prohibit link posting for Brand New&Newbie accounts, forum would have more benefit than harm from such rule.
