I tried using this tool for a new project, and the results surprised me. I registered several accounts on unreliable SIM cards and bought proxies (I used cheap shared ones, but honestly, for reliability, it's better to get individual ones – I just got lucky that the accounts weren't banned). I found chats for inviting and launched the invitations. In 10 days, out of 5 connected accounts, one was banned, and the others are still active. During this time, I managed to invite about 4,000 users, of which around 50 made a purchase. The costs quickly paid off, and in the end, I ended up with a good profit. The tool really works; the key is to approach it correctly. For example, I found great chats with a warmed-up target audience for inviting.
