It is apperently also used for other purposes because Zultrax is in no way Zultrax is a greedy client but it still would get dispreferenced.

Futhermore it is not a very efficient way to reach that goal because it can easily be avoided as I alredy described.

An alternative and more honest way to shut up greedy clients might be actually looking at the traffic a connection is generating. Compare the number of queries, the number of queries with hopstaken=1 and the number of query responses with a recent average and you easily filter out the ones that are greedy. We also include the number of pings in that because some send truckloads of them around with no clear reason.
