Recently I decided to try sale groups to promote my products. No links, only high-quality texts and photos. The problems started from the very beginning. Initially, my new accounts were accepted into several groups (I made 2-3 requests per day from each account, no more), but then (after 2 days) the process slowed down - I was no longer accepted into groups. Probably my accounts were in junk. How can this be avoided? What are the tips from experienced moneymakers for sale groups on Facebook?
