There is no scenario in which a site that accepts your mail (i.e.

The Yahoo postmaster help page for TS01 actually suggests suspending
all mail to Yahoo for four hours, and apparently some people believe
what they write.
That makes no sense at all, surely nothing more productive will happen
when the spiggot is turned on 4 hours later with even more mail queued.
The point is that "following instructions" is a reasonable proxy for
"being a legitimate sender". Spammers have no motivation to jump through
the hoops, as they don't really care about mail which doesn't get
through. Legitimate senders, though, have to if they are not to end up
with large numbers of disgruntled senders and/or recipients.
To be more specific, Yahoo's code TS01 doesn't mean "You are sending us
too much email and we want you to slow down". It means "We think you
might be a spammer, so we are setting you a simple test of whether you
can follow instructions". If you pass the test, then when you restart
sending then you'll be able to get everything through - it won't be
rate-limited by Yahoo.
