Look, I can "Google search" for an answer to a question just as easily as you can, but the number of answers here on Pets that are blatant text dumps from other sites, several without references back to the source, and many which are repeated multiple times on multiple external sites, the situation is simply getting disgusting and discouraging.
Certainly link to another site; take some relevant info if you need to, but why isn't there some active paraphrasing going on instead of what appears to be blatant reputation whoring and filler? It's lazy and I don't care for it. I want to see QUALITY answers, not QUANTITY.
For the rest of us, before you up-vote an answer, grab a sentence and throw it into your browser's search engine, then call the poster on it if it shows up somewhere that isn't linked to.
This question asks why this is going on and what is to be done site-wise. I have created What should we do when we find unattributed text? to discuss what we should do with these posts on an individual basis.
