If you did 21 blitz offer on swagbucks, did you find another site to do it on as well?

Hi, I completed it on swagbucks. I got credit for it on a another website called ysense. A few days after, i was banned. I wonder if that's the reason? I reset my phone before doing it as well. I want to try it on another website named inboxdollars, but i mean..don't want to get banned there too. Thanks for any comments. stay safe
