Everything to fight trolls in the ways like email requirements is gonna hurt genuine users more and just cause mild inconvenience to spam bots and trolls as temp mails are quite easy to ise and only genuine users are not gonna want to attach a temp mail to their acc . But yeah maybe a form filling like on .ml and that would weed out people like "jewkiller" etc. and would work better overall imo.
Edit : sigh Let me guess the downvotes because i'm using a new acc ? Well lemmings that is how it works everyone starts somewhere and doesn't spawn out of thin air with a year old acc yes you too had a new acc once . For what's worth you can check my history and see I in fact am not a troll just stop being paranoid as hell all the time .
Aww pepe looks hella cute
