i suspect that the person hammering you was using a gnutella servent called Qtrax2. this program is known to be an excessive hammerer and can send you packets many hours after you left Gnutella. although it gets no response, it still hammers you, it even hammers you if you are already uploading to it the file it is hammering for. it just hammers the whole time for no reason. if you were reusing the ip of someone else, it is possible that it tries to connect to you for over 24 hours. it is not in wide use though, as the gnutella community doesn't recommend it. it also has no forum here. decent gnutella clients (i mean every one i know) will mark your ip adress as unresponsive and not try to send you any more messages after a short timeout interval. raphael has even developed an anti-hammering feature which he built into gtk-gnutella, i think others will follow. so there is no need to have a beef with gnutella, it's a very nice network generally.
