Yes! However, it tends to get much more likes than it does retweets, as is the nature of Twitter. For instance, if you order 10-20 likes/retweets per post, you won't get 20 likes and 20 retweets on a post; it would probably be closer to something like 18 likes and 3 retweets. The numbers will be different every time, but you can expect a lower number of retweets than likes.
As far as we're aware, Twitter does not prohibit this service. They haven't been very outspoken against services that help users grow their profiles, and our service is as safe and organic as it gets. Twitter frequently updates their terms of service, however, and it is up to you to check their terms of service. Our service is legal to use in every country that we know of, but it is also up to you to make sure that our service is legal in your country. We've been growing Twitter profiles for over 8 years and have never had a single issue with banned profiles or anybody getting a notice from Twitter about our auto likes service.
Unless you tell them, no, there will be no indication that you're using our service. If you go from getting a few likes per day to hundreds per day, some of your followers may take notice, but this isn't necessarily reason to suspect that you're getting outside help. There is no mention or branding of our service on any of our work, and we're promoting your page to real human users.
We'll get to your new tweet very quickly. It varies campaign to campaign, and based on your posting habits, but we'll generally have your post promoted the same day, if not the same hour. If it's taking a while for us to get to your new tweets, please contact us, and we'll look into it right away.
