If it is a the case that jesuashok was doing this to aid in his teaching program then it implies that he's not overly bright. He would get answers much better suited to his purpose (and questions too) if he noted in each case where the material came from and why the answers it had received already were not appropriate to his purpose.
The fact that there are a good number of plagiarised questions asked by madtoperl and answered by jesuashok mitigates against that being the motive however. Current thinking puts the two of them as workmates or similarly close associates in some fashion. Surely if they can coordinate enough to post and answer questions in synchrony, they can communicate well enough to not need to engage in behaviour that they ought to know was not approved by this community - they had both bumped against this particular behaviour standard in the past after all.
They both showed up yesterday. Neither wrote something or turned up in the CB.
