Hi there! Last months I faced the same situations. A new account is warmed enough and website starts to receive a significant amount of traffic, let's say 4000 daily. One day traffic increased by several times, to 15000 daily. And after a day or two traffic dropped more than ten times, to 1000 daily and got stuck there. Almost all traffic that stays, comes from repins. Fresh pins bring almost 0. The account is active, the website is not blocked. I suppose it's some kind of shadow ban. Has anybody faced the same problem? Any advice is highly appreciated.
