I decided to try Spam Guard because I was really fed up with spam. Recently, bots on Instagram have been out of control. I was satisfied with the results. First of all, I didn't have much trouble with the settings, even though the interface is in English; I still figured out how everything works. Secondly, I managed to clean up my follower list, blocked the spammers, and, oh miracle, the ads under my posts have practically disappeared.
