Their Subscribe-Star Page says the "Super-Sponsor!" - Tier at 8.50 USD gives access to it - and the higher ones, too, of course.

Well, if you can read the link and it's a valid subscribestar link even when hovering over it, you are winning at the media/internet literacy game, after all - and if it weren't the proper link, it would have been removed by now - as all others seem to have been by the devs/moderators! So, differentiating between scam links and links, that help the team, would be a really helpful skill - for those alarming as much as those reading them, wouldn't you agree, @midnightlua21 ? Generalizing this, insinuates most people are too ignorant or unskilled to be capable of doing that, i.m.h.o. - and I do not quite think so, despite me also having been utterly disappointed by many people's (willful) ignorance in the past. But I believe people can grow smarter and learn to recognize scam-links from links, that are valid/helpful.
Still: thanks for reminding people to at least be careful before clicking links - that I also recommend doing.
But I literally copy-pasted the link to the Devs' Subcribestar-Post where it shows which Tiers are eligible for the advanced version with the extra fiend. Feel free to check it yourself by using the Devs' Subscribestar-Link, then go to the post and compare the two links (mine and the one you find) and then tell me, if I was trying to deceive anyone again please.
Thanks for your differentiation and concern for people's cyber-security - both can exist at the same time. But mistrusting everyone generally doesn't lead to good places in a Society/Civilization entirely founded on trust...and specialized so much, that each and everyone of us depends on thousands to millions of people trusted enough to do their jobs well enough so hardly anyone of us dies from their neglect, mistake (humans make those and the smart ones learn from them and try to mitigate their consequences if they can).
