I could keep my mouth shut, but I'm feeling rather opinionated today. Hmm.....maybe even one of those *b* words. I have had this person post this stuff in my groups more than once, and I've seen the same in others. Joined my groups, with applications that said they were looking forward to talking with other bird lovers, but then never has anything to say, just posts a link to their website, which didn't even work properly when I tried to look at it.
I think that if someone is going to try and promote something from which they will have a financial gain, they really shouldn't expect any support, unless they are willing to actively participate in the groups where they are advertising. These groups aren't about making money, they are about sharing information.
