Description
Hide listings from sellers you never want to see — on search results and on the personalised homepage feed. Marktplaats only lets you filter listings IN. Every filter it offers — brand, condition, delivery, price — narrows results to things you want. There is no way to say "not this seller", "not this brand", "no dealers". Zeef adds the missing half. BLOCK A SELLER IN ONE CLICK Hover any listing and press the ✕ in its corner. That seller disappears from search results and from the personalised "Voor jou" wall on the homepage. The homepage feed carries no seller information at all, so Zeef looks it up once and remembers it. HIDE PAID PLACEMENTS Admarkt is the channel auction sites and resellers buy their way into your feed with. One switch removes all of it, without a single extra request. WRITE YOUR OWN RULES Filter on price, distance, city, category, business versus private, words in the title or description, and per-category attributes such as brand or model. Rules can be limited to one category, so "no BMW 3-series" does not quietly filter your book searches. HOW IT FILTERS Blocked listings are removed from the data before the page draws them, so nothing flickers and no gaps are left in the grid. Where something is unknown, the listing is shown — Zeef only ever hides on positive evidence. WHERE YOUR DATA LIVES In your browser and nowhere else. No account, no server, no analytics, no tracking. The only permissions are storage and access to the three sites it runs on: marktplaats.nl, 2dehands.be and 2ememain.be.
