<p>GSIs and professors alike notice that kind of thing… It’s usually quite obvious. It’s just that they aren’t obligated to take time out of their teaching to tell them to stop. If they want to sacrifice a letter grade so they can gossip on each other’s status updates, then that’s their choice, haha. A GSI telling a student to quit it is kind of like bailing them out. Though in some classes, the GSI or professor will just say right off the bat that they won’t tolerate the use of computers for anything other than taking notes, completing assignments, or researching relevant information during class.</p>
