Do you mean when a twitter account is unable to follow more than 1000 users per day? Please share link, where did you get this info
I have not heard of such a rule, but don't worry anyway we use special instruments for twitter activity analysis.
Just a fyi its real and it causes extreme drama at the end of the campaign. See the loyalty coin bounty if you doubt. A lot of managers in other bounties are now recognizing this issue and taking corrective measures. It must be a fairly new policy by Twitter.
Thanks for being here for our questions. So far this looks like a great campaign and i'm glad to be here.
