What a bunch of cry babies about the free $50 btc. When you go to the site it clearly states how to get the $50. It does not even have a "name" for it as you say it because that is what the complaint was a long time ago. A bunch of people said they didn't like the name "welcome bonus" because you don't get it immediately when you sign up. So they removed the name, but of course internet always finds a way to complain.

Yeah, i don't get what this complaining is. It's perfectly normal and anyone who is visited in mores then one of these gambling sites would assume that any signup bonus comes with conditions. Usually at least with 1:1 deposit and at least 50x wager amount. I've seen way more dishonest advertising then this. At least Earnbet is telling us what those bonus conditions are.
