2008-01-24 - ISRAEL USERS
Unfortunately it seems, that a few Israeli ISPs, are intensionally altering the announces to our tracker of their clients, announcing to our tracker false stats (over 8.000.000 TB of upload and download) in order for these users to be probably banned (and save some bandwidth). We made a script to automatically detect this false announce, and reset the user's account (reset uploaded/downloaded). Although this is NOT a fix, only a temporary solution, we cannot do anything more from our part, since this is not a problem of our tracker. We know that reseting these accounts is not pleasant, but the other alternatives were to ban these accounts or to ban all the Israel Golden Lines ip block (which unfortunately seems very possible in the future, since our tracker gets hammered because of the problem above)
Seems most of the users having this problem use the ISP-> GOLDENLINES
