Voted Yes, not only because I'm one of those idiots who got hacked, but also because it is beneficial to see all security and privacy-related threads put in one place, into one board, rather than scattered all over the forum. Easier for everyone to gather information.
I also like the idea of placing it on Others. That way, it's much easier to notice than placing it as a sub-board of Wallet software. Others is like the middle-ground between Bitcoin-related topics and Altcoin-related topics. Users will be able to discuss security and privacy-related topics for both Bitcoin and the rest of all the Altcoins on it; placing it there just makes sense.
