“Is it safe to use?” question
Question:
Is it safe to use?
Will my social networks accounts be suspended if I autopost?
Is it some kind of Blackhat SEO tool?
Can I use it for mass postings?
Answer: SNAP is not a spam tool. SNAP is not a Blackhat SEO tool. SNAP is not a tool for bypassing any rules of the site where you are autoposting. You need to follow all terms and guidelines of any site or social network you are working with.
None of the networks we support suspend accounts simply based on the fact that you are autoposting there. Do not post spam or content that is not allowed, do not post more posts then allowed, do not abuse the network in any other way and it will be fine.
If you account got suspended for abuse/spam or any other reasons, please contact the social network directly, we can’t explain why that happened.
Most of the networks (Facebook, Twitter, LinkedIn, Google+, etc..) act on user reports. It means if people are clicking “Report as SPAM” buttons on your posts, you will soon start receiving notices and account suspensions. It really doesn’t matter for them how your posts got there manually or automatically.
