Although it is probably the +most well known option out there, it is certainly not the best. + +## The security issue +Pastebin has a couple of issues that harm the visitor's security. This on +itself should be considered such a bad practice that no-one should consider +their service at all. + +### Cloudflare +Cloudflare is a [MITM][mitm]. It completely breaks the secure chain of TLS on +the web, and should not be used. Any service still using Cloudflare should be +shunned. There is [another article][cloudflare] on this site which has more +information on this specific issue. In addition, Cloudflare can be considered a +privacy issue for the same reasons, as is detailed below. + +### Advertisements +Another issue with regards to security on pastebin are the advertisements. +While it can be argued that "they need to make money somehow", using ads always +seems like the worst possible solution. Especially given the way they're +serving it. The past couple years have shown that advertisements on the web are +easily abused to serve malware to good netizens who decided to not block all +ads. + +A rant on the state of ads might be appropriate, but this article is +specifically about Pastebin, so I will just keep it at "third party +advertisements are a security risk, avoid sites who use them" + +## The privacy issue +Apart from their security issues, Pastebin also offers some privacy issues. As +stated above, they make use of Cloudflare. This means that whenever you visit +them, Cloudflare takes note of this. They may even decide that you need to +perform some additional tasks in order to be allowed to the resource. This +doesn't happen to most users, but if you're using any anonymization practices, +this will happen almost every time you visit a site behind Cloudflare. + +In addition to telling Cloudflare, you will also tell another third party, +Google, in case this "additional step" is required. This is done via the new +reCaptcha system which will inform Google of almost every detail of your +browser and the behaviour used to solve the puzzle. Incredibly useful for +fingerprinting you accross multiple locations. + +### Then there is Tor +But, if you're using an anonymization proxy such as Tor, even if you do not +care about the Cloudflare issue, and you solve the "security check" presented +to you, Pastebin still refuses to offer you their service. If they are going to +refuse you service, they should tell you up front, not after you have already +informed two other harmful parties of your attempt of accessing the resource. + +Actually, they should not. They should simply not require you to give up your +privacy and serve you the content you were looking for. Blocking resources to a +certain group of users is simply censorship, and should not be the status quo +on the free internet. + +## Alternatives +Luckily, there are plenty of alternatives that do not treat their users with +such disrespect. I ask anyone who is still using Pastebin to stop doing this, +and use any of the alternatives. + +* [0bin.net](https://0bin.net/) +* [cry.nu][crynu] (works like termbin: `nc cry.nu 9999 < file`) +* [ix.io][ix] +- [p.tyil.nl][tyilnl] (works like termbin: `nc p.tyil.nl 9999 < file`) + +[cloudflare]: /articles/on-cloudflare/ +[crynu]: https://cry.nu +[hastebin]: http://hastebin.com +[ix]: http://ix.io/ +[mitm]: https://en.wikipedia.org/wiki/Man-in-the-middle_attack +[termbin]: http://termbin.com +[tyilnl]: / -- cgit v1.1
