I came here to post the same problem but seeing as how there's already a post about this happening to others, I'll just add my two bits to this thread.
I suspect that at some point I must have posted something that either had the wrong word in it or a link or something and ended up being deleted as spam either in my own blog or in another WordPress blog... which means that Askimet has been "taught" that I am spam.
Over the holiday, I posted about it here:
so people would read about it and know to check their own spam bins for posts of mine. I hoped that if I and others were going into the bin and un-checking me as spam, that Askimet would be "trained" back into knowing I am not spam.
This hasn't worked yet and have been doing it for several days now. I don't mind having to go to my own spam bin and retrieving my own posts at my own blog but it means that I can't be free to comment at other wordpress blogs because how would I tell them to go get my post out of their bins if they don't as a rule, check them?
Does anyone know how long this might take or what I can do to get back in the Askimet "good graces"?
Thanks for help!!!!
