Looking for the old blog, I think it was on Blogspot, or even just an archive of the guy who was growing mold cultures on his roof YEARS ago, and would update and post pictures frequently.
I found it on /x/ originally I think, before the split. The guy started having respiratory problems sometime through and found out it was from the spores I think, and then started getting questioned by the feds when they saw the blog because they were toxic
Been wanting to read through it again, but can't find a trace of it anywhere
