It's probably because you're not able to successfully ARP for them.
Your ethernet interface is probably configured for the network
209.53.0.0/18, so other ADSL subscribers are considered to be on the same
ethernet segment as you. Everything else (not on this network) will be
handed off to the default gateway, which you already have an ARP entry
for.
Try adding a host route for the other user and see if that helps. For
example, if your default gateway is 209.53.13.254 and the other user is
209.53.44.16, try...
# route add 209.53.44.16 gw 209.53.13.254
#
Alternatively, you could try setting a static ARP entry for the other
user's IP address with the MAC address matching the MAC address of your
default gateway. ie...
# arp -an
? (209.53.13.254) at 00:00:00:01:02:03 [ether] on eth0
# arp -s 209.53.44.16 00:00:00:01:02:03
