- The post contains links to illegal or pirated software.
- The reported post has the only porpuse to advertise for another website or another product.
- The reported post is off topic.
- The reported post does not fit into any other category, please use the further information field.
AFAIK the report feature is used to report whole threads as well. If that's not the case skip the first one.
In any case this is a few additions I can think of:
- The reported post is about a topic allready being discussed in another thread.
