Are you implying that there is some kind of plot to flood the hotlist with a certain program? I too used to think such repetitive programs are bots, but lately I've been more convinced it's actually some CS class doing projects together or something. Especially as all of them have only 1 vote.

Hi! I took a look at these programs and it looks like they were created by users in the same school, so this is probably a class activity.

They all have only 1 vote, so there's no vote manipulation being used to get them on the Hot List. The Python programs (and that version of the Browse Projects page) are still relatively hidden, so that's why programs with low vote counts tend to appear there.
