If i understood well your fist email, you need to check current version of all ruwiki pages not necessarily the 'last minute' one, as a once check. You can download the ruwiki dump (last dump is of a month ago, but surely a new one will done shortly), which is 87.2 MB (102.8 MB if you also want discussion and user pages).
So you download it, have your computer running for two centuries ;-) measuring it and, at last, upload the results. Even if you update it once a month, doesn't seem so exhaustive...
