Funny enough, at least one person dms me everytime I post a review and pretty much insinuates it didn't happen, which is like the best compliment I could ever get. Since I run my reviews past the provider before posting, and many are on here if only semi-regularly, I just send the non-believers directly to them. No one has ever come back with a question of legitimacy after that.
Imagine if social media closed everyday at 6pm like a shop ... We will all be forced to socialize with family, friends, go outside, do some activities ...
