I am seeing more evidence and excitement on Bluesky than Mastodon about Brazilian users migrating from Twitter.
What are you seeing?

It's been a long time since I was invited to leave Twitter, and I left (now I'm the happiest person in the world in Mastodon). Now they invite me to leave Reddit... where am I going? #twittermigration #reddit #helpmastodon
How to delete all your old tweets from twitter/x:
I'm using the third party app TweetDelete. One must download one's twitter archive first to then upload a file to TweetDelete to then task it to delete them all. I paid for a month to do this.
(I've no affiliation with the site, I'm just using it to avoid trying to delete thousands of old tweets by hand.)
