Yes, it happens on this site all the time..and I have learned to recognize them so well..that I either respond with a negative email...like "come on...challenge me with some original and more intelligent material." Other wise I just delete their emails, ecards, and flowers. I am so used to it..that it really has no negative influence on my experience on this site anymore....as if they were not even there anymore. They are like mosquitoes...just showing up and I just swat them away.
I think most of the regulars on this site are the same way.
Good luck and God bless!!
