I recently posted a review of a vendor that I've been messaging, and in part of my review I stated that the shipping was a little slow and was at first concerned if the pack would show. After the resolution, the vendor messaged me later stating that he had multiple buyers asking for reships and complaining about not receiving packs even though he'd only had one previous complaint ever (me being his second) in months of vending.
So, vendors, do you see a new influx of orders after a review or customers complaining about certain things like shipping speed, stealth, etc.? If so, it seems like a review can lead to negative consequences for the vendors if buyers try to play on the negatives of a recent review, like asking for a reship because the pack hasn't shown even if it is simply the buyer trying to turn one over on the vendor.
Not a Vendor, but reviews on Reddit will effect them on some level.
I generally regard the reviews on this Sub-Reddit with some amount of trust (as a person who contributes reviews) and will make decisions on purchasing depending on the reviews in the sub.
