A few reasons why I allow it (and why the 1% of the communities have NO restrictions on bumping/necroposting is Nintendo 3DS Central) are:
#1: I really don't care! Is it such a bad thing to revive a 5 year old topic on Super Mario 64 DS to post something that relates to the topic at hand? I just don't care!
#2: Considering how quiet and small Nintendo 3DS Central is, it doesn't matter how old a topic is, and whether or not it contributes much to the topic or not, ANY POST IS A GOOD POST! It isn't feasible to restrict posts on topics after a certain age when member activity is already so scarce (in fact, the only member who isn't an alternate of my account who currently posts here on a regular basis, to a rate that actually exceeds MY OWN is @cm2! He deserves a medal for that!)! Any Administrator of a small forum that they pour their heart and soul into maintaining while they are ALSO paying for hosting, a domain name, and (to those it applies to) the forum software would agree!
#3: This reason makes it a few reasons why! If I come up with other reasons why bumping is (and will always be) allowed here on Nintendo 3DS Central, I'll let you know!
