Everything is working fine

This app is by an entity calling themselves

https://www.invitelikecomment.com/en/

Problems:

1. The site above ^ does not itself have ANY Facebook link,
2. "Invite Like Comment" does not show up under that name in a direct search on Facebook itself, either as a phrase or one word.
3. The site refers queries to a gmail address
4. The format reeks of scam
5. An DMCA accreditation button links to a "suspicious" result from 1 of 79 malware engines, Quttera significantly enough? Possible false positive but anyone can get one free, and it smacks of window dressing.
6. There are four community posts, two with serious downvotes.
7. The privacy page does mention any legally binding jurisdiction, just brief promises. There is no official business name listed, or any company of that name at opencorporates.com

Overall, the picture is not good. Recommend: avoid.
