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.

this can be done, and it’s suspect when someone’s done it to build a following and it’s not clear if they own the tweets. 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.

Unreliable datetimes is just part of AT and something you need to deal with. The moment you start ingesting the firehose you'll see plenty of backdated or forward dated traffic. If you build feeds you need to be careful when using posted timestamps to sort feeds because of backdating and because there's no real centralized way to verify your timestamps. For my feeds I just reject posts that are beyond a certain delta from now and sort my feed by ingestion time rather than post time. 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.

Well, if the source is publicly available, anyone can copy it anyway. So, you need anyway to announce on the original account where it has been migrated to.

PS: I had a similar migration idea when bsky came out, but never thought they would allow backdating. 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.
