While I wait for stamina to regen I check for cases. Sometimes I get lucky and get 6-10 in a row but it is more like 3-4 every 10 or 15 minutes. Plus I get the "so sorry your too slow" occasionally as well. not all fast clickers are macro's. Looking at my open list I have 2 friends that are very active and show up a lot but they still get beat by some of the less active friends that click a little bit faster. But yes id one "friend is the ONLY one clicking and you have several active on your list, it can get suspicious. Don't rush you can message the friend and ask if all else fails before kicking them. Happy hunting y'all.
