Actually, since the selection intent was for it to be random, which has potential for selection bias, and then going on and having specific communities repost the survey, then there's no longer any potential for bias... We KNOW there is a bias at that point. It becomes a proven fact that there then is a selection bias. The only question that is not yet determined in regards to that is, what effect that bias had. And the thing about bias is that it's impossible to know, hence why studies with bias, are outright thrown away by anyone that is actually trying to find the truth of it.
There's nothing here!
