Patreon for hosting fees and then outsource the maintenance work to some people that want to help. There shouldn't be much maintenance for a scraper website, updating links and xpaths.
Such a bummer, the post says its just a matter of time he doesn't have to maintain, would have totally backed it with a monthly patreon or something like that. There was someone in these forums that was making a game dev job search too, anyone remember the name of it?
