The Twitter Berlin Wall just went up.

Im glad to be here in West Mastodon, under the careful leadership of Prime Minister #JohnMastodon, but we still need to help our friends and family stuck behind the wall escape.

(And that includes blocking/banning/defederating the malicious actors coming along with them.)

@Crell per the East Mastodon government, it’s not correct to call it the Berlin Wall, it’s simply an Antifascist Protection Policy, for the good of the residents.
@Crell Unfortunately, this policy change will make the existing migration tools less useful because they rely on the info in the profile that Twitter has just forbidden.
@bugbuster42 Yes, there's an arms race going on now.
