I agree, there are already too many sections and boards on this forum. There is no need to create a new one for a specific type of service. Mixers fit best in Bitcoin services.
Exactly, that is why I said that adding another board could only create more confusion, we still have them a lot more than I would like to see.
I am not against having separate board or sub-board for Mixers and Privacy talk, but let's not spread attention in to many boards, better group them in one section that already exists.
I think there are too many boards which are basically the same. For example:

And there are many boards inside those. Do we really need a Ripple board and a ripple news board? A BAT forum (this should be inside ethereum>erc20 imo)
These subsections can logically be placed in different global boards or main sections, so when searching in a correct board and not finding some can despair and decide that there's no such topic at all. So for some sections there is an additional redirection in other most expected places.
For the user experience, this is a terrible solution. Going through the forum regularly, I see the same things over and over again. It seems quite illogical to me.
Maybe these would be negligible things if we had the possibility of ignoring/hiding certain boards or child boards.
We, users of the forum should not be victims of better SEO and adaptation for search engines.
I don't even think those SEO techniques are effective. It is quite the opposite IMO.
SEO techniques, when implemented correctly, they improve user experience, not the opposite. I see that in websites I have worked.
