While browsing various hashes couple weeks back i noticed in the reviews someone was going round giving 7/10 to at least couple different vendors hashes and this happened all same day.
Imo it's gotta be one of the vendors wanting to bring their competitions review scores down.
Us buyers are only interested in getting our smoke and when that happens we're usually that chuffed we can't help but to praise the vendor. At least i do, even when i bought on street i looked at vendors as local heroes.
Anyways when i see review scores like 5/10 and know myself the product is good i see it as probably another vendor.

Although poorly worded, they may mean previous buys in general, not specifically previous buys from you.

There should be a way of vendors to contact the reviewer whilst still keeping them anonymous.

Ordered for first time from this vender and received a day later, the best bubble you'll find around! Is top quality service with top quality product plus packaging, A*!.. I got the wedding cake and will be watching out for what bubbles BubbleHashKing does bring next ! A beautiful golden ball.. trust in this vender, is legit for sure x

I’ve not tried bubble before but just now it’s a bit pricey. Is anyone jumping in?

It's a red flag the vendor had a different hash type up on the wall now its weddingcake a would give them a miss if i was you

That looks great. Are you going to be offering any samples?
