Rules

How the wall works

One wall. It never gets bigger.
You pick a size and a spot. Poster and Large can go anywhere open; the one Billboard owns the centre. Your poster goes up there and links to your site.
Poster $1, Large $2, Billboard $25.
Every click your poster sends is counted and shown publicly.
Anyone can paste straight over your poster by paying 1.5× what you paid, rounded up to the nearest 50¢.
Pasting over takes the whole poster. Nobody can cover half of yours and leave the rest.
Once the wall is full, the only way on is to paste over somebody.

There is nothing to upload. Your poster is printed from the one link you give us.
Give a website and we take its largest icon as the logo, its theme colour as the background, and its description as the strapline.
Give an @handle — or paste your profile URL — and the poster links to your X profile and uses your profile picture.
No theme colour? A colour is picked from a fixed palette by hashing your link, so your poster is always the same and the wall stays varied.
Artwork is read once, when your poster goes up. Changing your site later will not change the poster.

Your poster stays up until somebody pays more. There is no time limit and no expiry.
Being pasted over is not grounds for a refund — however long it was up for. That is the whole game.
Covered posters keep their place in the list below the wall, with their link and their click count intact. Being covered is not being deleted.

Card payment through Stripe. We never see your card details.
If somebody takes the spot while you are still in checkout, your payment is refunded automatically. You are never charged for a spot you did not get.

Product sites and personal sites.
No link shorteners, no chat or group invite links, no sexually explicit content, no malware, and nothing illegal.
Tracking parameters are stripped from links.
Anything breaking these rules comes down without a refund, and the spot goes back to bare wall.
