but I had a hunch that there was something off with the way those two keep finding reasons to mention that particular wallet. It just doesn't seem natural.
Yep. It's one thing when you see someone mentioning Metamask or MEW, two widely used wallets, and OWNR is complete opposite. I honestly don't know anyone that trued using it, and if it weren't for signature campaign I would probably never heard about it.
It looks like they managed to stay under the radar for quite some time because of the way they were doing it.They are not necrobumping threads or posting out of context like many spammers do. The threads they are posting in are about software wallets, suggestions and recommendations, places to buy and store coins, and things like that. At first glance, it seems like everything is ok, until you realize they are doing it regularly, but not too much to arouse suspicion.
They didn't mindlessly spammed either forum or their threads, making it much harder to notice them. So yeah, this thread bumping and prmotion is level above classical shitposters that are doing this kind of thing.
Beside them, I think that there is a group of high ranking accounts doing the same thing but on much higher level. The only problem is that they are doing pretty good job making it really hard to connect the accounts and certain threads where they are active.
