I get a lot of spam on my Wordpress blog. I work on french blog for a music band call Trio BBQ, so I get a lot spam regarding food. I know that more comments you have better it is. So I decided to modify the comments in wordpress so it's doesn't look like spam, and I delete the spammer url, because I don't what the he get a backlink from my site. Should I continue to do that? Is it a black hat technique? Thanks for the response.
