Maybe this is nothing new, but I just noticed a lot of new reviewers (4 or less reviews) getting EU votes on pretty poor or at least below average reviews (and poor grammar). This in stark contrast to the usual complaint of experienced and skilled reviewers who get Somewhat useful reviews on above average or EU reviews (ie: someone has 20+ EU votes and 1 lone SU).
It does raise an eyebrow.
Are people just being generous, because they are new? or something else? They are not really doing any favors to them long term, if their reviews need improving by voting EU on a mediocre review. Same as voting excellent on an editor, who might be a friend, when the review is full of mistakes.
