3 is untrue. Discord blocks or requires tons more verification steps for most VPNs and blocks VoIP numbers.
I have been trying to use Discord anonymously for a long time. Antispam and anti-logging are high priorities of theirs, and they invest significant resources into ensuring you can’t easily make disposable accounts.
Not only is it not “so easy”, it’s not easy at all - it’s extremely difficult and becoming moreso all of the time.
You’re opening yourself up to blackmail by hundreds of different parties.
It is blatantly irresponsible to host such communities on Discord. Possession and use are federal felonies.
