As someone employed by OWNR for writing I highly doubt they would pay people to shitpost on bitcointalk about their wallet.
I wouldn't be so sure about that. Two accounts that have been asleep for a long time wake up to tell the Bitcointalk community over and over again how good ROWN wallet is? I seriously doubt that. I confirm Pmalek's observation. Yes, I've also noticed those two spamming on several threads, but most importantly, they create off-topic replies. They don't participate in the discussion. Instead, they usually just throw some non-sense responds, one line each and they never get involved in that topic again. I doubt that they'd answer you if you quoted them.
Exactly. It's one or two sentences mentioning the wallet in combination to whatever the topic title is. So, if it's about storing crypto, they will say store it in that wallet. If it's about purchasing coins, they'll say that you can easily buy coins with that wallet. Right now, whether we want it or not, this thread is advertising OWNR wallet.
To be honest, I never mentioned the brand because I don't want to advertise it. NotATether and you did. 
I reported a few posts to see how the admins would react. From 6 reported posts, 2 were deleted and 4 reports are still unhandled. I guess the admins don't see it as too big of an issue or they are still unsure about what do do. However, the unwritten rule is if the report is left unhandled, it's almost a bad report, kind of soft-bad.
