> Enthusiastic students have no one to mentored and direct them and it makes them act on lot of bad advice. In my college, sophomores teach freshmen about Google's Summer of Code, open source and events like hacktoberfest. These endeavours are headed by the one or two guys among the students who happen to get into GSoC/ICPC or (in majority of the cases) have a good competitive coding profile

In my mind the problem lies with the college, they should be teaching their students how to contribute meaningfully. Spamming behaviors will only hurt the reputations of everyone from that college.
