Not sure if you've tried or felt like using the "report to moderator" button to have other review guides moved to have a uniform policy put in place. The reasoning behind the report could be that your were moved and this would be inline with prior moderation.
I have done so. The reports were ignored, and posts questioning it were deleted almost immediately (this was a while ago).
If I were to offer an opinion, I feel that all review/guides would all be suited to the mining support board. Mostly because they also serve as a guide for the particular hardware. This also allows for a stream of support Q&A's to post in the thread.
This was what was done - or tried to be done - in the time before my setup guides. But questions would *always* leak into hardware, if not in their own threads, then in the announcement thread of each product which hardware still has to have. It just became a messy repetitive Q/A in 10-100 page threads without any actual content. Its not ideal to have setup guide/reviews in hardware, but it seems to just be a reality that they're necessary.
Unless there is something drastically different, why would 1 piece of gear need more than 1 topic in the hardware section.
The vast majority of product announcement threads (which would be the 1 designated topic) are just "Hey, now selling x miner. Go to y website to buy" and don't provide any content, information or support on how to use the darn things. That leads to the giant unuseable threads I described above.
First off don't think I've had the opportunity to say thanks. I read and reread your S4+ and S5 threads multiple times as that's what I started out with last year. (Fanboying over lol)
Trust me, I would reread my own threads to remind myself how to set up on some hardware after it was moved. And sure miners are a bit more UI friendlier than they used to be, but everyone is still slightly different, defaults to different network topology etc.
