(This is more a question about sources than tags themselves, but since it's part of the info you add to a post, I suppose it also counts. If not let me know and I'll correct the category to General)
I have noticed that, when I post my arts, giving my BSky post as one of the sources, people edit the link of the BSky post to another one.
For example, they change
https://bsky.app/profile/jmluxro.bsky.social/post/3mfnkmkqgrq2j
for
https://bsky.app/profile/did:plc:7mcqnbf32ipbrazzntiamid2/post/3mfnkmkqgrq2j
Both work the same way as far as I can tell, so what is the reason for the change?
