I know I have seen this mentioned on another blog. Your followers comments going to the spam folder instead of your post. Or, your comments not showing up on other blogs. I found 4 legitimate comments in my spam folder this evening.
More than likely their comments or yours have been marked by Askimet as spam. I was unaware of this and I am guilty of some practices that might get me marked as spam. This is an excellent post on the problem. It contains other links with very useful information. Check this article for possible solution if you are marked as spam.
As I said, I am guilty of some bad methods mentioned. I thought it was being friendly but apparently short comments, and certain words in your comment, can cause you to be marked by Askimet as spam.
I suggest checking your Spam folder from time to time for legitimate comments. It’s a little more work, but it prevents us from missing friends, that might have been dumped in there. If you have comments you make not showing up on your friends blogs, contact them (perhaps by email) and ask them if you might have been sent to the spam folder.
Comments welcome,
