moderated comments!

K I just thought that I would tell ya all why my comments have become Moderated and ask all you other blogger if you have the same problem!
someone keeps putting porn links in my comments! It is really starting to tick me off! is anyone else having this issue? I love to read all of your comments except for ones that have naughty links! well I just am getting a little fed up and wanted advice from you awesome ladies out there in hairland!
