IMHO the way you ask for re-seed is what it should be. When we get complains about frequent repeated requests in short time by the same requester, it is what I advise him to do in future (as a first friendly step of Moderator action).
With the high minimum ratio requirements here, I am quite sure that everyone who got the file and knows how to re-seed will do it. However not every member is looking here each day.
Requesters should keep in mind that they send up to 120 PMs out to members they don't know, a kind of "Spam" in some members eyes.
Anonymous members are either Power User, who have chosen strong privacy level in their Profile or higher (read Moderators, Retired Moderators, Administrators, etc …)
Sometimes the Staff members may send Re-seed requests, to see of a torrent is definitely dead. Not all can leech immediately or at all (a question of bandwidth and ratio, I don't mean me). Sorry for that, but you will know it by the requesters name.
