Twitter Rate Limiting
usatoday.com> Verified accounts "are limited to reading 6000 posts/day," while unverified accounts were limited to 600 per day, Musk's tweet said at about 1 p.m. ET Saturday,. New and unverified counts will have an even lower limit of 300, he said.
I bet all of those recommended tweets that one is otherwise not interested in viewing will be counted against this quota as well.
