Looks like there is a problem with one of the forms of the apostrophe '. (Probably the Unicode one not the ASCII one).
"Going advanced" allowed me to post anyway - so that looks like another loophole...
I generally use the three dots character (Alt+0133= ) does the autocensor work backwards I mean, does it check posts already made and fix (i.e. FUBAR) them too?Yeah, you could say that.
More accurately, the security hole involves using non-Latin characters.
