Giveaway locked due to suspicious activity

[test]

Often when I try to do the Feudalife challenge game I get "Giveaway locked due to suspicious activity" Sometimes immediately when I try to play and sometimes some seconds after the game has started. It does it in bunches so if it's locking right away or a few seconds in it will keep doing that pattern.

When I can actually play is actually rare.

Why is it that you require a phone number to use Discord? Very frustrating.
