Is source/citation shaming against the 'rules'?
I often see people link a source for their information when people ask for such and then people hand wave such sources off. They say they are not "credible" sources.
This is partly why I rarely, if ever, link sources to my information. People will just say they "don't believe" the source or simply discredit the source. It is easier just to have the person have them look it up for themselves.
