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, patched by some:

discord://%64%69%73%63%6f%72%64%2e%67%67//invite//anondrop Uses the discord protocol, only works in apps
