It used to be the go to to buy/sell used items, but now it's a real Joke. Searching for items has become more and more difficult since they just give you 4-5 legit search result and the rest is Ads from paid business like wayfair.ca (which is just a company that drop-ship cheap items from alibaba at high price).
Selling or offering service is a joke too, any excuse is good to delete your ads unless you pay. And anyway there traffic stats don't lie, they are dying slowly... At this point in time, just use Facebook Marketplace, you'll save yourself trouble...
