I think it might be confirmed then, so at least people can know why their name is crossed out and don't have to worry about it or feel singled out now. The 100-200 is a guess, I didn't find any examples with 99, 100, 199, 200, 201 posts yet to narrow it down, but there are people with around 50 or 250 posts that aren't crossed out.
Using actual numbers, you can get a good range from the following two posters:
73 uncrossed, 224(226-2 in this thread) uncrossed
101-223
And it's fixed, that was fast, for me anyway. I have a dm from a friend from 9 hours ago.
