You’re missing the big impact here which is that bots can shift public opinion in mass which affects you directly.
Gone are the days where individuals have their own opinions instead today opinions are just osmosised through social media.
And if social media is essentially just a message bought by whoever can pay for the biggest bot farm, then anyone who thinks for themselves and wants to push back immediately becomes the enemy of everyone else.
This is not a future that you want.
You can’t really tell.
It’s also a very very VERY small platform compared to other social media platforms like Reddit. (I had another comment where I calculated this but it’s ridiculously small)
It is unlikely that it would see anywhere near the same level of dedicated bot activity due to the low return on invested effort.
This is a problem that will become greater once the value of astroturfing and shifting opinion on Lemmy is high enough.
