I have been using it for a while now and to be honest, when the bot first came out, it was great. It did just enough things for me to get done what I needed done. But for the past month or so, the dev. department has been slacking BIG time, and while they've been slacking, other bot producers pretty much filled the void.
Not only have the new bot producers filled the void, but they have a lot more options on the bot compared with Botstagram. Last but not least, the owner of the bot is flirting with the idea of making people pay for major updates to the bot, which wasn't mentioned from the beginning.
Not looking great for them at all, IMO.
