Hi, when I follow someone I usually do this from multiple accounts, with different servers and platforms. This is partially as backup. It’s also because different software has different features. E.g. at the moment of writing I mainly post from my Friendica server, but it doesn’t yet support polls, or account migrations. So I also follow from my Pleroma server, which does notify me someone has migrated.

I also sometimes use platforms that support nomadic identity, that allows my channels on multiple servers to be synced. From software that doesn’t support that, a follow request looks like multiple separate requests from those channels.
