You know how you send links and get blocked? like discord.gg/anondrop? there's an easy way..... use > to add characters between the link. Use < link > to format it as a link example:
> <http
> ://
> disc
> ord.
> gg/
> anon
> drop>
Second bypass i found:
https://discordapp.com/%2569%256e%2576%2569%2574%2565/%2561%256e%256f%256e%2564%2572%256f%2570 double-encoded, not even discord detects it as an invite
Third somehow:
https://discordapp.com/a/../b/../invite/anondrop
