Don't read what you don't like, easy enough.
The thread is what it is.
Has the guy actually run a race in a year and a half? Probably not, but so what? Everyone knows he cheated and won't admit to it, OBVIOUSLY.
If people want to post, let'em. Why does it bother you so much? Simply ignore the thread until the guy fades away and then comes back and runs a race 5 years from now, surely denying everything.
It's like the library book that was never returned and the person avoids the library for years because they owe a fine. Then years later they show up to check out books and deny everything saying that they'd returned it years ago. That's what will happen, trust me.
