The corner is a mediocre deterrent at best, but watermarks over the image I do not go for. It's a slippery slope, very hard call to make, etc.
At the end of the day, the pictures look much better and less distracting without the watermark. No watermark may not be a tenable solution however.

Up to you MPM, this stuff is your baby.
