Just FYI there is a discussion behind the scenes with the OP about this.
There are 2 facets here - posting this thread for promotion and not using the winner videos one is a bit naughty and Bryan has already mentioned that above, he has apologized and will in future use the proper thread like other streamers - sorted, all cleared!
The second facet is a bit more convoluted - as Dionysus and the OP have mentioned in our discussion, he is not promoting the casino of the same name and has owned the casino-land domain for a while. This has lead to an unfortunate situation which can often arise when you buy 'cut-and-shut' domain names. I'll explain:
When setting up a site, you obviously want a really good and relevant domain name with a good keyword. For example, if I wanted to buy 'onlinecasinos.com' it would have been snapped up 20-odd years ago and if not presently being used would be traded for a fortune! It is a premium and desirable generic casino domain name.
So knowing or seeing that one wouldn't be available for 10 euros like most domains when I went to a domain purchasing site, I then try (what I consider) to be the next best thing i.e. 'online-casinos.com' with the hyphen. Now if you check, Google don't like this and you'll see the un-hyphenated version will usually rank higher then the original, all other things being equal. Now naturally, having bought the hyphenated version you will not call your new site 'online-casinos' but either online casinos or onlinecasinos, removing that inconvenient hyphen and also removing it from your site's meta tags and search keywords. This is not something I would recommend that any webby's do, but it does go on. A bit like buying 'casino-meister.com' although that's a brand name not a generic title so is far worse than my initial example.
This is all well and good until it conflicts with the un-hyphenated premium version as it has here. You are naming your site without the hyphen while having bought the hyphenated version of the name, cheap.
I accept that the OP is 100% straight here and did not foresee this issue and has been a bit unfortunate in that the chickens have come home to roost in this case. Remember, it's ownership of the name that's the cause of any issues, not the timeline of who did what first!
To that end I have suggested a solution that means a very small tweak to the OP's changed name and would not cause any future issues with the casinoland gambling site. I am awaiting responses, it's the seniors' decision and we can await their verdict.
