Lemmy feels less anonymous than Reddit, because there are less users and its easier to be remembered. Similar to a small town where everyone knows each other.
i have the theorie that there are even way fewer users here than people think, at least when it comes to posts not commens...there is a cluster of accounts that kinda feel like they are all run by the same person.
theres less need to creat alt accts than reddit, because reddit or the sub will ban people often, also throwaway accs arnt really a thing on lemmy compared to reddit, for the above reason. originally throwaway/alt is to avoid getting your original account getting brigaded or ban for one reason or another. now with reddits recent updates thier filters are so sensitive its easier to get ban if you look at it wrong.
i made multitudes of accts for different niche subjects to avoid any cross-potential interaction with controversial subs. but reddit recently starting looking at everyones account and banning any account that has been partipating a sub they were previously banned in, or if any of those accounts had spammy posts.
