um...this topic is located in
Home / Other / Other / Off topic
and we're debating wether it's "allowed" to be off-topic? If you want to keep a topic on-topic you don't ask how topics go off-topic, because then YOU are switching the topic to why topics go off-topic and making no attempt to keep things on-topic. The only thing that would keep a topic on-topic is on-topic posts.
And the fact that it's in the off-topic forum basically means it doesn't matter anyway.
