Much appreciated, but wouldn't this allow anyone to "migrate" somebody else's tweets over to bluesky, basically impersonate them with 1-click ?
What's missing is some sort of verification.
There's probably some sort of blockchain-based time-attestation like [1] that could help but this is beyond the scope of AT and something that probably needs a lot more thought before a serious proposal comes forth.
Who is the "you" here?
Probably someone who started ingesting the firehose
I came to the conclusion that it would make sense to confirm a user's identity on the platform to migrate from (egress) by giving them a random word or sentence for them to post over there, so you can verify that their original profile is really theirs.
I tail the firehose sometimes , filtering for post dates that don’t contain 2025. Bottom line this has been happening since day one and backdated/imported posts were about 1/16th or so of the overall post volume in any random sampling I’ve taken. It’s a lot.
But the few I spot checked , all checked out. The people importing their posts were all mentioning their new bluesky on LinkedIn or Twitter . I haven’t caught a spammer yet. It’s something I look at when I am extremely bored.
