It seems that Akismet is malfunctioning, and spam-marking a lot of comments.
I was recently trying to post some (very long) comments at http://tpproposal.wordpress.com and they were not appearing. I informed the site owner about this on another site (TRF, a physics blog (on blogspot) written by Lubos Motl), and he said that they were all appearing in his "Spam" folder.
I'm having the same problem while commenting on https://mcmahondemystifiederrata.wordpress.com .
The only solution is for me to inform the post authors outside of their blogs, which only works if I know them outside their blogs.
Can this problem be fixed ? .
