I have been running classic since 1995 and I never had anyone get in my forum and create any problems. I have had others on my servers as well running classic and still have 2 classic boards running on my servers and still no problems.
I agree to a point depending on the classic version.
The real issue was the spamming in my case.
In his case it looks the same.
So options are close the board to guests or just turn off notify posts and give users another avenue if needed. Like a help forum.
Either case if spammers can find a email address they will use it.
