This site tried to install MacKeeper on my mac, when I tried to install a mod. When most reviews are 1-2 stars, with only 1 or 2 reviews that have >4 stars, how is this site still rated 4.2???, and how is it safe, with adfly, shorte, and adfocus.

Steals mods from official (trusted) outlets, adds in malware/ad revenue generation, and in turn makes money off of the mods instead of the author. Site also claims to have versions of modifications that don't even exist, like "Railcraft for [newest game version here]!" for example. Basically, they're thieves and malware distributors making a profit.

The site steal content that has been made by other people and post links to it on their site, bypassing any attempts the original creator of the content has made to monetize their product. 9minecraft infringes the copyright on thousands of 'mods' for Minecraft that have been made by people on minecraftforum.net. They place many ads and lie about the compatibility of the mods. The site deletes any comments that tell others of their true nature to hide how illegal they are being. This site should be taken down.

This is a site that rehosts Minecraft mods without the mod-maker's permissions. They SEO optimize to fool people searching for mods that don't exist (such as "RedPower for 1.7.10"). It is at best a low-effort leech site using SEO tricks to fool kids, at worst, who knows what they've put into the stuff they host. Modmakers have complained that they take ancient versions of the mods and present them as new ones.

9minecraft.net's ToS contain the following sentence: "Our softwares are owned by 9Minecraft.Net copyrighted and are the property of 9Minecraft.Net." Several Minecraft mods, such as WildBamaBoy's Minecraft Comes Alive or Chimaine's MobTalker 2, are hosted there and are definitely *not* 9minecraft.net's property. Furthermore, the company's details are not given at all, making the site even more suspicious. In addition to that, most mod authors forbid anyone except themselves to reupload or redistribute their mod in any way. What 9minecraft.net basically does is reuploading and redistributing mods. I do definitely *not* trust this site at all.

They rehost mod files rather than linking to the original download. This is illegal and against mod licenses in many cases, and even if it weren't it is bad practice, as the rehosted versions are probably outdated and the mod developers don't get the ad revenue they deserve.
