I've seen a few recent posts, usually blatantly obvious, where a new casino appears and is very quickly praised by a bunch of new accounts. It's a very shallow attempt of advertising and should be an instant warning to stay away. One of those sites also used a registered trademark of another gambling company, which is a red flag that they will be shut down one way or another fairly soon. It's worth having a flick through any links in the footer of the page and having a quick read through, because shell scam sites will often copy pages from other casinos or may have dead links throughout. If the support page is comprehensive (phone numbers, addresses, people) and you are able to do basic verification on it  - even just simple Google searches that match useful results - that could save you a headache in future.
