15 Beaches that are no longer safe

I participate in a FB group called "westjet Customer Service and Complaints."
You can probably tell by the title that this is very definitely NOT a FB group supported by the Canadian airline WestJet. It's a site where air traveller's can "air" their grievances of lousy service from one of Canada's two major airlines.
Two odd things occur regularly on this site:

1.Someone purporting to be a WestJet Customer Service rep. responds to specific complaints, asking that the complainer contact them for assistance in resolving their complaint. These are scammers. They are NOT WestJet employees and are in no position to resolve anything.
(WestJet may well monitor this "bitch site"......I'd be shocked if they did not...but they very definitely do not respond, in any way, shape or form.)

2. What is really odd, and most frustrating, is that a bunch of clowns from Nigeria constantly post totally false, totally negative stories about WestJet, complete with photos......stories of air crashes, labour troubles, flight cancelations, pilot and mechanics strikes, senior executives quitting or being fired, etc., etc.....all lies...or else dredging up year-old stories of labour
strife, etc. The originator of this crap is https://naijasitemarket.com....a Nigerian-based group.....and usually sent by someone named "Seyi Osunlana".

Needless to say, WestJet does not fly into or out of Nigeria.

So the question is: why are a bunch of Nigerians corrupting this FB group of complaining passengers of a Canadian airline? The only guess I have is they have been hired to spread as many lies and untruths as possible, with the intention of destroying any and all credibility the FB group may have. And who might benefit from destroying a FB group embarrassing to WestJet?
