We used to have a forum science thread to find and unlock the fifth trust level, A.K.A The Cow Level Trust level 5 - the cow level
The whole idea was to post something and like every single post it had and back then when it was active, I ran out of likes on a daily basis 
I think the cap was around 50 likes / day back then but it might be that it has been increased since then.
Edit: Maybe we should do a similar thread to find out the flag cap per day 
. “Twily, I have an idea…”
