The interwebz is a crazy place. These forums are so well moderated and frankly some of the nicest people you would ever want to glean a little info from! In the small amount of time I've been here, I help when I think I can and have been on a quest to learn as much as I can and apply it when I hit road blocks.
I think this place rocks!! I don't care where you look for info, you will always find "that guy". He's done it faster, better and cannot/will not be corrected. It's always nice to learn things by doing, but with this ever evolving hobby we enjoy, you have to be ever dilligent when safety is involved.
I don't own a mech but I'd like to think if I wanted one, I could operate it safely. I also know, if I had any question about doing just that, I could easily ask it here and get a response very quickly that would quell any uneasiness I had about my choice.
In my short vape life, any and all questions have been handled with respect and enthusiasm. Not saying that I have not seen what you have described, just don't find it to be the norm and when it does happen, there will be 10 other responses that more than make up for one misguided one!!
