Obvious consequences;

– you can speedrun all your visits

– pick 12 forums carefully (i.e. synchronise everyones visits) and noone needs to lose out on pistachio

– raid takes same amount of time no matter how many players are running their visits, since everyone raids simultaneously (unless they have a bucketload of alts, in which case it’s always going to take a while)

Basically, it’s fun to earn mega scoops, but the game mechanic here means no challenge. It’s just the same as running visits on your own, and there’s not even a lemon or pistachio tradeoff.
