In my opinion, all casinos that charge additional withdrawal fees on top of the standard network transaction fee are just typical scammers.
Gambling should be the source of their income, not manipulative fees. They're not a fucking bank, but a casino!
How about the site you are promoting on your signature space?
Will you say they are typical scammers because they charge you 0.00025btc while it is higher than the current standard transaction fee?
They charge 0.00025btc, but what purpose? you also have to realise that.
I can say about freebitcoin, they cost a little higher fee when you make a withdrawal request but you can't blame them for that. all of those fees they use to boost your transactions.
How could you give them blame when they didn't take anything to their pocket!
Better you could do, request them to add a feature by which you can set the fees manually, when the maximum number of users will report the same issue they may think about your requests.
