Mmmm, I always treat each H&S reply on a case-by-case basis, and I didn't feel that this one deserved secret tags. The room is relatively straightforward, the person asking for help merely needed assistance on roach smiting techniques, which shouldn't be secret in my opinion. Also, the original poster essentially revealed the solution in their post, so it's already been spoiled.
So, I respectfully disagree.
Game on,
