Hi there; I've recently started a new blog and have received spam comments (It seems like they put their (example) reallybadbackpain.aduse) etc and sites with advertising on them. Since I am using wordpress; I have the ability to edit before I approve. Would it be wise to edit their names; delete their links and post a comment that looks like it is helpful, and then in return I could reply to that on my own time so if someone was to see the blog they would see that there are people who are commenting and saying things that are useful? My blog is in the "wellness" niche so I think it would be a crucial part to have a sense of community so to speak. Can you be penalized for this/any drawbacks to your site getting ranked/indexed?
