Copy and Paste Galleries

I am often embarrassed in situations where I give a user's post a compliment,
only to find out that their galleries are just "Copy and Paste" galleries.

If that's too cryptic for you then look at it this way...

You go to your favorite video or photo channel.
You view a video or photo and you really like it a lot.
You leave a comment like "good job" or "can't wait to see more of her."
You view the user's profile and you discover that all their videos and/or photos are completely different in every way.
The quality, the resolution, the different environments or settings, etc...
Some even have watermarks from the websites they were taken from.

Then you realize; "Wow! And all this time I thought it was the user who made it and posted it...
and like an IDIOT, I complimented him on his work."

Don't you just hate when that happens? I know I do.

What are your thoughts on this?
