Sipsy Flabber remains uncontested

One month ago, back when only a small handful of nine-letter words were written, a brave Ape named Sipsy Flabber wrote our first ten-letter word - "contraries". And not only is this word impressively long, it even appears in Shakespeare's The Tempest:

I' the commonwealth I would by contraries
Execute all things; for no kind of traffic
Would I admit; no name of magistrate;
Letters should not be known; riches, poverty,
And use of service, none; contract, succession,
Bourn, bound of land, tilth, vineyard, none;
No use of metal, corn, or wine, or oil;
No occupation; all men idle, all;
And women too, but innocent and pure;
No sovereignty;

I didn't make note of it at the time, and expected a few more 10 letter words to trickle in on a weekly basis, but nope! It's been a full month and Sipsy reigns supreme (if largely unadorned):
