I agree that this poster is often just very blunt with his opinions. However, from the few posts of his I have read, I have seen that he does not hesitate to put people down and name-call, which IMO is absolutely not helpful in any way. Need an example? //www.curezone.org/forums/m.asp?f=86&i=843
Note the "these pathetic women's posts" line... and his tone is usually quite degrading (again, in my opinion).
Anyhow, as a regular curezone user, I now avoid the forums he frequents. I am not suggesting he should not be able to post, but I do agree with Lapis that the warning was appropriate.
