Give option to not allow links in DM's.

I get a ton of spam messages of people wanting me to join their discord and check out their project on their website. I also get some great messages from people in the community that need help or want to make trades, etc. So I don't want to have to close off my dms but I also don't want to get 100 spam messages a day. All of the spam I get has a link in it so if there was an option to not allow links in dms, this would avoid that. A lot of dm links are harmful anyway because they could involve hacks.
