Hey, that's the gereatst! So with ll this brain power AWHFY?


Few tips to control spamming,

  • Approve your comments manually
  • Make your blog nofollow
  • Install comment system software like Disqus

Maybe just bots looking for blogs that allow comments through, so they can be added to a list that will later be sold and/or abused.

commenting over blogs is a good idea to increase back links but your comments should look like you are not spamming it over google.
Too much commenting over the blog is also not a good deal for stable ranking.

More over you should write comments but it should be website friendly.
