Please look at d-h.st and billionuploads.com, both have good speed.

Please add netload.in in your list, don't count it inside other sites, I just use it and sharebeast if possible after the problem with turbobit which delete everything on it

It's significantly easier to change a number than to reverse engineer the uploading process of another host.
I like AnonFiles for fast upload speeds and that they keep files for a long period of time.
7z wrapping is of no concern to me, as the code to do it is already functional and quite stable.

I'm considering adding another host, but when I actually get around to doing it, I'll evaluate the choices then.

Personally (hint: rant incoming), I don't really like CloudFlare. I've been blocked out, myself, a few times, probably because I disable Javascript and cookies by default (and the CF redirection page chucks a fit if you have those disabled).
However, they sell themselves as a free solution to easily protect websites against spam, hack attempts, DDOS attacks all whilst making your website load faster. So many clueless website owners just set it up without thinking of possible implications (or why it's being offered to them for free in the first place).

I've never used CF so I don't know what they're like. But presumably their spam/hack protection is, at best, based on heuristics at the HTTP level - in other words, completely sucks.
Most sites being dynamic these days, I'd argue that the CDN caching is of limited benefit, although caching dynamic content in the event of the site going down could be interesting (depends on how often they update it though). I'll give them the DDOS protection claim, assuming an attacker can't easily get the underlying IP by sending a phony DMCA complaint.

Privacy is another concern as they're essentially sitting in the middle capturing everything, including all sent messages, everything any visitor views, and even authentication tokens (and possibly username/passwords as most sites don't hash the password before sending (like AT, but we have SSL so it doesn't really matter :P)). It's interesting that you have to pay to use SSL on CloudFlare, but even then, they intercept everything (probably so that their redirection pages work) so HTTPS doesn't protect your privacy there.

wouldn't it better to just replace anonfiles.com with davvas.com ?
its 5GB max upload file size without acc and no need to 7z files either :)

CloudFlare is causing a lot of distress and unhappiness to quite a lot of other sites for blocking users to some website on suspicions of automaton bots/spiders.

It's usually in response to complaints. Easy way to solve things...
