I rewrite articles and don't necessarily need to know about the topic I am given. I manually change the words, word order and so on, so it reads well and passes Copyscape. However, research never was part of the deal, so I don't see why I am forced to include it in the gig! I can see some issues down the line with this. My rewrites do NOT include extra content and I have only had 2 or 3 people (out of hundreds, maybe thousands) ask for it, in which case it costs me time if I want to accept it. If it's a food/drink or health piece, that's fine but if it's something technical or whatever then it's a pain. Who comes up with these changes? Why not instead focus on buyers being able to accept a gig offer without the seller having to disable their out of office and then turn it back off.
