I downvoted this for the reasons I stated on the other thread PX linked:
"I don't think that private messaging would be very good for the site. It'd probably cause unnecessary drama at some point, and there's no way we can moderate it. A decent portion of the users here are younger, and while I'm not someone to be all like "predators are everywhere on the internet!!!!!! strangers are all dangerous!!!!", but things like that do happen, and adding a private messaging system would make that a possibility here, where, without it, if we see anything strange going on, we can quickly deal with it. This is a Pokemon forum website, there shouldn't really be much of a need to discuss anything privately. Using something made specifically for messaging, like Discord or Hangouts, would be a much better experience, anyway."
I feel like a private messaging system would cause much more trouble than it's worth, and stuff like sexting and possibly even grooming would almost definitely happen at some point, which is something we don't want on the site at all. Especially with grooming, it'd be insanely difficult to stop because it can often go unreported. I'd also like to add that the only people on this site who can't use any other form of social media are people who are 12 and younger. There's probably a reason a lot of sites require users to be 13+ before signing up, don't you think?
