For me, ProstoSpec is an old and trusted boosting service. I've always appreciated two things about it: the support for various platforms and the huge range of boosting types. The first is important to me because I boost accounts not only on VKontakte, Instagram, Facebook, etc. There are dozens of services for boosting on those platforms. But I also need TikTok, Yandex Zen, Twitch, Periscope. Finding reliable services for promoting them is difficult, but ProstoSpec boosts them all. The second is the types of actions during the boosting and their quality. For example, on VKontakte: you can simply order the cheapest follower boost, or you can go for the expensive one, with criteria and speed.
