So far, I considered this just a nuisance, until a spammer sent an email entitled "16,000 Woodworking Plans and Projects", claiming to be from "Wood Gears", with the return email address of firstname.lastname@example.org (not my email address). The mailing address included was for 750 Hornby Street, Vancouver BC. Googling that, it's the address of the Vancouver art gallery. I doubt the art gallery has anything more to do with this scam than I do.
Here’s a traditional Swedish farm accessory for gunk-laden soles. The dimensions are not critical, but be sure the edges of the slats are fairly sharp?they’re what makes the boot scraper work. Cut slats to length, then cut triangular openings on the side of a pair of 2x2s. A radial arm saw works well for this, but a table saw or band saw will also make the cut. Trim the 2x2s to length, predrill, and use galvanized screws to attach the slats from underneath. If you prefer a boot cleaner that has brushes, check out this clever project.
