What the actual hell is wrong with the Sign-Up system?

So I was creating an Alt Z8Games account today, but then I noticed that each time I insert a forum name that is not used and longer between 3-12 words... It gives me this message: "The Forum name Contains Prohibited Words" But why it always gives me that message? I mean I tried names like: GgGgGg and AAAAAA and CCCCC etc... I tried all simple names that don't mean any insult at all... So what the hell is wrong with the sign up system?!!
Edit: I just tried again now, it now gives me this message: "The forum name is already in use" each time I try a code name that no one ever used like: APDGN5464 or ASGA6G486 or 161a6763 etc... any name I use it says that it is in use, So why?!

Spammy names with the same character too many times in it. Try an actual name.
Also how do you know your input names aren't used?
