it’s a tricky line to run so I see your concern.
I mean right now your site is fairly well respected as being unbiased and not compromising to the testing. Such that most of us solidly know there isn’t a maker selling a product review.
Even the few times you had a vendor give you equipment to review as always you state it upfront and in a informational manner.
So having a spot for vendor reps does potentially color that. I think it if was over here in discussion only - they were not allowed to buy into the system as a “supporter” it might be OK and stay good. But you run the risk of that branching out - especially as you start to have “store sales” etc.
I’m cautiously for it. But only on the discussion side and like above - no social media.
