And here are stats of lemmy platform where it shows that we gained 200 000 lemmy users in 2 days:

Another tracking site with the same explosion in users: https://the-federation.info/platform/73
What do you think? Is it some sort of a bug or do people run bot farms?
Edit2: It's been now 3 days and we went from 150 000 user accounts 3 days ago to 700 000 user accounts today making it 550 000+ bot accounts and counting. Almost 80% accounts on lemmy are now bots and it may end up being an very serious issue for lemmy platform once they become active.
Edit3: It's now 4th day of the attack and the amount of accounts on lemmy has almost reached 1 200 000. Almost 90% of total userbase are now bots.
Edit 3.1: my numbers are outdated, there are currently 1 700 000 accounts which makes it even worse: https://fedidb.org/software/lemmy
But the question "why" strands. 200 upvotes will get you on the front page at the moment. Why not stop there, why make your bot accounts so conspicuous that they are basically garenteed to get deleted?
Because it's easy. Someone is just testing some basic tools, to which they can add countermeasures later.
