Heidi I get these all the time … Mostly I think they are spam bots that float around the web sending website forms and blog comment forms. I have a capture question on one of my websites we thought it might help cut it down at bit
http://www.breakofday.co.uk/contact.php, it probably does stop a few but on Art In Wax http://www.artinwax.co.uk/contact.php I didn’t have that but did code not to accept links, and in my blog all comments have to approved.
I never reply to any as then they have your email address !!!
What gets me is even the ones that may not be bots say "we can get you on the first page of Google " especially when it comes to hubby sites (we have a decorating biz and have 3 websites for this) I think did you not check !!! We are on the first page of Google !!
I totally agree it’s really annoying
