Think he was just being sarcastic.
Report a lot of posts and be a very active member of the community and theymos may ask you eventually.
Out of curiosity, how active were most staff members prior to being asked? Does he he count alt accounts?
Well their levels of 'activeness' will have all been different, but being active is probably the biggest requirement (but that comes along with reporting lots of posts). If you look at the table with the most reports some of the pre-existing staff hadn't reported
that many (MiningBuddy only had 108 in July for example). And by taking alt accounts into consideration do you mean the total of reports over them all?
