Followers are your pubkey mentioned in their contact lists, you can have as many followers as there are pubkeys. Your contact list is limited in size though, just like every other event kind, strfry has 128Kb max event size IIRC, others' may vary but there will be some limit no matter which relay. And the bigger the list, the more expensive it is to edit it, which makes increasing this limit not practical anyway.

Sorry yeah I meant follows (contact list). Very interesting to know that there's a limit there. Merci ! So if someone follows you that's quite the honour in a way (1/2000) hehe 😉. This limit could be useful for spam protection as well. I'm going to have to think about this more.

Well that honor could be diluted by their ability to include you in other profile lists and switch btw them :) Limited CL size also helps with requests to relays, when you know you won't have to ask about 100k pubkeys to build the home feed. It probably helps in many other places. But then it's a less 'general' solution than unlimited list, might limit some use cases. But then 'follows-based' home feed might just be a legacy twitter-like approach and we might end up with a very different set of "filters" to build one's main feed. Just rambling
