User was multi-accounting. Is multi-accounting a big enough issue to freeze an account generally? No. But when multi-accounting is being used to abuse a giveaway/promo/limits we will take action. This wasn't even two or three accounts but dozens of accounts being used to abuse promos.
If stake.com want to freeze account/ban the site should
"Not allowed user to login" instead of
"Not allowed withdrawal". Because when user/player did not know if they account was ban and make some deposit
they just getting scam by stake.com.
