Any artist has the right to make money out of his/her work. Having said that, as long as clipart sites charge exorbitant rates even for standard memberships,dedicated teachers who do not have commercial concerns won �t bother.
I haven �t seen teachers ever stating here something like "I don �t own the copyright for the images but they are licensed under creative commons…" Under all of the pictures we see " Copyright © date- copyright owner Publication or redistribution of any part of this document is forbidden without authorization of the copyright owner."
The disclaimer automatically recognizes that uploader as the copyright owner of the whole worksheet including the images.
The moderators � job is to look into the reported worksheets. The site �s duty is to abide by the legal copyright rules. What I question here is the role of members whose sole purpose seems to be reporting worksheets without contributing much themselves.
