I'll have to say that, for myself, I haven't had those kinds of problems at BetterMost.
Oops! I realized later I did once. More than a year ago, I got a PM from somebody containing some very harsh criticism -- about a particular post I'd written as well as all of my posts in general. The PM called me "arrogant," and what made it particularly hurtful was that this person said that "others" also felt the same way about me. Who were these "others"?? I got this sense of a bunch of people talking behind my back about what a jerk I am. Maybe everybody secretly thought so! It was a terrible feeling.
So I wrote a post about it in the thread this PMer was talking about. I didn't name the PMer, of course, but I said that someone had told me I'd been arrogant and obnoxious, and I apologized to anyone else who had taken my posts the same way.
Well, the response was very reassuring. I got a bunch of posts and a lot of PMs from people saying they didn't agree with those criticisms. And in the end, I felt a lot better. So one person -- oh, and maybe a few "others," whose identities I never determined -- didn't like my posts. Plenty of other people said they did.
And the critical PMer and I wound up coming to some sort of peace and getting along OK after that.
The moral, I guess, is that if one person or a few people don't like you, a lot of other people probably do. And even that one person may have lashed out impulsively and will eventually think otherwise.
