I recommend Trastik for purchasing permanent links, especially if you work with adult content, pharmaceuticals, gambling, and other topics that are often banned on most similar platforms. This doesn't mean that all topics are allowed, but at least they don't offer blatantly illegal ones (like drugs and similar). Moreover, the prices on Trastik are not inflated, and on average, they are lower than those on Goget or Prseip. Additionally, there is a one-year guarantee against removal: either they will refund your money or repost the link for free. However, you shouldn't choose overly cheap donors, as the quality will correspond to the price. When searching for sites, the URLs are not visible until payment, but you can use filters to select by ICX, TCI, domain, trust, and so on. Articles can be purchased in the same way. I often encounter negativity regarding Trastik placing links on problematic sites, which is why the prices are low. Personally, I don't know if that's true, as either I've been lucky (even I didn't dare to choose the very cheap ones), or such sites don't appear at medium prices. I've always had everything in order; the links weren't removed, so I didn't have to use the guarantee.
