I am satisfied with the software; updates and improvements are released regularly, and the first update came just a week after purchase. The program costs almost 2500 rubles, and there are no time usage restrictions. It works well in conjunction with Lparser from the same developer, which I purchased a while ago. Linviter lacks a built-in parsing function, but it allows working with pre-prepared lists. I recommend considering the purchase of additional software. The program is convenient, but it can be difficult to understand right away. The package included a manual for all functions, which took me a few days to study. The interface is pleasant and fully in Russian. I use the program cautiously to avoid blocks. With the settings, you can set intervals so that invitations or likes are sent less frequently during mass liking; it's also advisable to use proxies until you can avoid sanctions.
