Pay for customer reviews and comments?

Hey guys – long time ghost-reader on these forums, I don't really say much as I feel like the people who post know so much more than me!

Any how… I have set up an online store and we do well via SM advertising, but I did notice another business who gets 1000's of comments on their videos and ads that seem artificial.

I was wondering:
1. Are there any good ways to get reviews paid/non-paid?
2. Will google or Facebook punish paid reviews?
3. Should I just focus instead on just making more…
