I think it's b/c unlike other forums, HCB doesn't have enough mods or have mods who are active

though, they should give a reason for deleting the thread. I do read the rules but sometimes you get stuff deleted for petty reasosn like the Harem Heroes sub forum if you look at my sig

banning non users wouldn't much of an issue for an active mod or 2 where I lurk. Some forums disable the non user system.
