The first time I heard of mosprognoz was because of this thread, which I thought was very well done:

It appears he likes to take the initiative as far as doing "undercover" investigatory work is concerned, so unless if he's done something that's actually scammy, I'm not going to remove him from my trust list.

He gets a bit carried away sometimes and hopefully he'll be a bit more careful before leaving trust ratings going into the future.

I tend to look at net totals when considering including/excluding people from my trust list: are they doing more good than harm? If so, I would say they are a net positive for the forum, and worthy of inclusion. That's how I feel about him at the moment.

Nobody's perfect. Everybody makes mistakes.
