How to get check mark in the verification screen

when you go to verify let say on my server https://restorecord.com/verify/BeamersParadise there is the check mark near the name and on other servers that use restore cord they dont have that check mark so I was just wandering how I got it

if you have more than 1000 verified members you will get a verified badge

oh thats nice thanks for the fast response. also to transfer members to another server the custom bot has to be in that server too?

yes
