hotlog.ru and some subdomains appeared in the SURBL data yesterday, but the site is also ranked about 25k on Alexa so it seems to be a fairly popular site. A couple readers of Russian took a look at the site and determined it's some kind of web log analysis tool vendor, but could not easily say if it had legitimate uses.

Is anyone here familiar with them? In particular might they have legitimate uses?

It's been around since 2000:
