What are these new presumptive botnet clients doing that degrades Tor

Is it just that they're building circuits that don't get used?

Or are they (as elrippo noted) DDOSing relays, rather than actually
building circuits?

How does having four times as many users affect the vulnerabilities that
Johnson et al (2013) identified?

What could those new presumptive botnet clients do in order to improve
anonymity without degrading performance?

I wonder if the presumptive botnet owner might start running some exits
just from self interest. If this were a botnet, slaves inadvertently
running exits would have highly plausible deniability, right?
