Miscellaneous topics that do not fit into specific categories.
I think you may have used some key words which are not allowed.
for example, I was trying to do a photo about "mother and son" or something like that, but Bing AI warned me (may be it no longer warns, but, I don't know) not to do that.
So, if you keep using phrases and you keep getting warnings (or may be you did not see those warnings), then, after a while you get banned.
Ultimately, these things are auto mated. You will just have to wait and see if you get unbanned. There is nothing else to do here.
Thanks
