I've been considering subscribing to his Patreon, since $5 a month is very reasonable and might as well start supporting him and collecting works sooner rather than later, but there's a fucking mountain of unarchived works behind a $10-15-a-pack barrier on his Gumroad. I cannot undestand pricing it that high, something like $300+ for the lot, nor understand how it's nearly impossible to find any packs floating around the web. I hope his works gets archived somewhere eventually.
From what I can find, there are a handful of pre-2018 packs people uploaded here and other sites, but outside of Twitter/Tumblr/DeviantArt uploads, there's less than a dozen Patreon packs or less saved anywhere.
