You don't specify a hostname but a pcap expression to tcpkill. The expression that's being used in this case is just example.com which is invalid. You'd have to use something like host example.com. Better yet, if you can use an IP address instead of example.com that'd be best.

With these expressions you can select traffic according to a wide variety of criteria, I suggest you have a look to see how things work. Incidentally, this is the same expression syntax used by tcpdump, so if you want to see which packets are being picked up by the filter/expression before using tcpkill on them, you can use tcpdump to test your expressions. Here's a reference on pcap expressions:
