My complaint is not with collecting the ACs; it's with trying to keep up with this fast-growing thread. That can be difficult if, while browsing, you see something that you want to 'like,' and then the very next one you want to do the same. One can wait 3 minutes or come back and try to find each message that you previously read. Then wait three more minutes to repeat the process. I do believe for the most part people are doing their best, but when you inhibit the ones who are trying to comply to prevent others from abusing the rules... well, one should be able to see the conflict.
PS. The timer is three minutes, not two. At least for me.
