Looks to me as though they're trying to get rid of the sub. In the past, they have made a decision on removing mods of subs and putting new ones in without too much user interaction, and they have never directly asked if a sub should be left to rot before.
The fact that the conversation can not be had without it being anon says a lot about the decline of Voat's community.
Plus if they ban the sub they then basicly betray the reason why people went to boat anyways. As there isn't really a legal reason to ban it (not an illegal topic it's a free space matter)
Basically it's lose lose for voat
