Yes! We'll promote your posts and help your photos and posts get more likes, and if you post a video, we'll also help that video get viewed by more users as well. The views and likes won't always be perfectly proportionate; for example, your video might get 310 views but only 280 likes. This is perfectly normal, and is the nature of Instagram. It would be strange if every person that viewed your video also liked it.
As far as we can tell by Instagram's terms of service, there isn't anything that prohibits third party services promoting posts or retrieving content automatically from an API. Our service (as far as we know) is also legal in every country that we can think of. However, it is still up to you (the user) to check with Instagram's terms of service, as well as your local and state laws, to make sure that you're not violating any terms or laws. Instagram frequently updates their terms of service, and while our service is fine to use now, that could change in the future. We've been growing Instagram pages for over 8 years, and have never had an issue with a banned Instagram profile or a message from Instagram about using our Autolikes service.
They certainly have the potential to, but it is not part of our service. If you get some engagement and/or comments from our service, it should be seen as an added bonus. We cannot control these users, but can only introduce them to your content, and if they find it interesting, they will like it. Once our quota is met and we've achieved your desired number of likes, we stop there. If you receive comments from that round of promotion, that's great! It's just not a separate service that we offer, and we can't guarantee that your new likers will follow you, comment, etc.
