When even the *BBC* start putting up articles about Twitter blocking Mastodon - you know the birdman has screwed up big time.

Twitter blocks users from sharing Mastodon links

The social media giant has also suspended the Twitter account of its new rival.

@mikegalsworthy That's funny. How many instances are there? They would have to block each one individually as there is not just one centralised instance.
@BogLoper @mikegalsworthy no they’re not blocking mastodon, as you say they’d have a problem with that but anyone posting a link to mastodon gets a warning saying twatter has determined that the link is dangerous I believe!
@weaniejeanie53 Not seen one as yet. Perhaps I'll go and look? But maybe I won't bother. I might be excommunicated. 😃😅😂🤣
@BogLoper I’ve seen a couple posted here by people who’ve received one. I’ve already been excommunicated over a month ago so I can’t look.
@weaniejeanie53 Just went for a quick look and - still there, in spite of all the Mastodon posts and links I've been posting. Haha. Secret squirrel. Shhh!
