I see a lot of copy-pasted content as well as very generalized remarks.

Something like "The project has a very small total supply. The ICO price is quite high. Hope the project will fly high when listing the floor" was repeated multiple times by the bumpbots. They also had various "good project" and "interested" replies at their disposal. By staggering these and repeating over and over, you can easily get 200+ replies quickly.

Since the accounts are disposable regardless they don't care about bans, hence the blatant plagiarism.
