Is off-topic not-related threads allowed here? (In general)

Well, a (few) seconds ago, I was thinking to make a Thread for anime character fusions, but I'm not sure if I'm allowed to post Threads with not-SmileBASIC related on general, so, just guessing.

kland.smilebasicsource.com Using the url bbcode leads to 404 smh

Lumage.smilebasicsource.com also allows off-topic threads.
