I do believe I have a follower or two who cross-post some of my stuff to Pinterest - I can follow the source of some people visiting my web pages. I don't have a problem with that: cross-post away.
However, today I got a comment on one of my older posts (one featuring e-cards which often use some adult language) warning me NOT to send any more vulgar language in his/her direction via Pinterest.
As I said, I don't post this stuff on Pinterest, but the beauty in the nasty comment? They left it as "anonymous."
What an ultra-maroon!
