I get a lot of comments, but a lot of them are just spam. But some of them sound complimentary, so for my self-esteem I may start approving them. Plus, some of them are kind of funny. One said that he would have given his right arm if he had found a particular post before he spent half a day searching.
But in order to prevent the spammers from getting any traffic, I edit the URL to point to my main page or the page that got the comment. I also remove the email address. Then I add some text indicating that the comments have been edited. Sometimes I only change the text if it is really incoherent.
