I've had the same issue! Any time I send a link to the Donald.win over mms in a group chat, I can't send any more messages for about 10 minutes. They just fail to send. I've had to do URL shortening on unencrypted chat if I want to send a link to this site. I am also on cricket. I have no issues sending messages with links over Signal. Luckily, I got most of my family onto Signal a couple years ago so I've been able to keep the red pills flowing to them.
