I disagree. Content theft is more rampant than ever. The only people who are truly bothered by watermarks like this are the ones who would be stealing it and reposting it without credit.
Not plastering over literally every single mm^2 would be a start, but what do I know, as a user/viewer, I'm supposed to just look and not criticize (according to the rest of the troglodytes).
You are free to say whatever you like, and of couse everyone else can agree or disagree with you. But apparently whoever disagrees is a troglodyte, so I guess you are always right. Didn't even notice the watermark till you pointed it out.
