Almost certainly.

I use tarpits probatively.
If I set up a tarpit, and the same host with several downloads in my
server logs also hits the tarpit several times concurrently, I block
them because I'm just burning resources otherwise. However, if I set
one up and it gets stuck, I assume (possibly over-confidently) that the
thing on the other end is running poorly-written garbage that is dumb
enough to just sit there. I'll happily burn a few kilobytes of memory
and almost no bandwidth to render a misbehaving host toothless.
Watching them blow up as they downloaded gigabytes of ASCII art (at a
disproportionately low cost to me) was _glorious_.
