Occasionally (but not always) an error appeared when I try to post something into this forum.
After clicking POST I get an error from the forum software:
Cleantalk: *** 1 Antispam service cleantalk.org ***
I have to go back (my posting text is lost :-((((() and have to re-enter the text.
The second post almost always works then.
I suggest to reconfigure your forum software
it happened to me few times too, so +1
CleanTalk is beyond control. It is a black box with an on/off switch I don't control either. It has been tried to disable it with the result that spam had to be manually removed 24/7, so it is as bad as it gets.
Hmmm, millions of other forums are able to filter out Spam successfully - without such messy errors.
I suggest to change the blacklist/anti-spam provider
It is confirmed. I guess, a problem on their backend. Fortunately, my browser (Pale Moon) does restore previous form content when using back button...
