This is ludicrous. Are they going to manually review every account now looking for social media links?? http://www.techmeme.com/221218/p5#a221218p5
Twitter will remove accounts made to “promote other social platforms” and content that has links or usernames to Facebook, Mastodon, and others

@caseynewton I have seen people use linktree and other services to showcase their links on #birdsite . So I guess that will still work for now. How long you cannot link to your own website as that might contain links to other services.

@caseynewton 3rd-party social media link aggregators such as linktr.ee, lnk.bio

Just read the policy link aggregators are banned as well.

@arshubham @caseynewton Linktree isn’t allowed anymore…
@arshubham @caseynewton the rules do also specify that link aggregation sites like link tree are banned too
