I feel I am hitting the #following button for the same people twice or twice

Is this for the #migration from a shard of the #fediverse to another?

@nolovedeeplearning Probably, it should automatically move people over I think but it seems there's a delay on this. Or it doesn't work perfectly.
@nolovedeeplearning I migrated an hour ago and it seems like it's particularly the accounts on @mastodon.social that didn't migrate correctly (both follows and following). I suppose the main server is overwhelmed.
@nolovedeeplearning thank you for following me 1082 times. This was not necessary, yet appreciated.

@ccanonne not necessary but sufficient

Do you feel you settled in the #fediverse? I can follow you all day long
