Leaving aside the concept of what is or isn't a gig, suppose that you're invited to do a floor spot, maybe an extended one, though you're not offered payment. Let's just call it a performance.

In my view it would be OK to mention this on your website as it's a pre-arranged event to which you can invite people such as other club organisers that you want to impress.

Would anyone object to that? For people like me who are just starting out, it's a possible avenue towards recognition, though I agree that it's misleading to advertise an unarranged floor spot in the same way unless you make it clear that it is what it is.
