I agree with you that upvote bots are not an enrichment for the platform and too many people upvote their crappy posts, which give the platform no added value.

However, we are on a decentralised blockchain, more or less on a free market where the set "Might is Right" applies. There was an opportunity to make money and people have used it. Everyone would like to earn money in this way and lies like anyone who denies it. Some individuals are concerned about the future of the platform, but most came to SteemIt because of the money. I would also prefer SteemIt without bots, but as you said before, this is currently unthinkable.

I had also delegated SP to a bot once, because my activity decreased and I found it great to earn some money with not doing so, quasi interest rates like at the bank, only much higher. However, people who take the platform serious and post daily and work hard earn more if they actively use their own SP instead of delegating it to bots.
I therefore recommend to all those who actively participate in the platform to withdraw their delegations and to enrich the platform with their own high-quality content.
