Idk. I’m one person and can only speak for myself. There’s thousands of forum members and thousands that read these threads everyday without a membership at all. Its honestly almost creepy if you think about it, there could be dozens of lurkers following you and making decisions about your practice and intelligence or deciding you’re just a fan fic read.
Lol I wouldn’t think to hard on it either way. They don’t need to affect your day, even if someone thinks your stupid. That’s life, sometimes people don’t like you and the best thing you can do is accept it and get on with what matters to you 
Especially with most internet peeps. If you’re never going to actually know them, then what they have to say really doesn’t matter two tiddly dinks, other than to let you’re mind be bothered by something truly non factor- without reason.
