I'd registered with this site last fall as a distant sibling had wanted a steampowered[removed by editor] card for her birthday. As the site appears to only support Paypal (instead of obtaining a legit merchant account from a bank) I ultimately decided to buy elsewhere. A few days later, I found that steamcarddelivery had added my address to an e-mail marketing list and sent me a solicitation offering a $3 discount in return for a favourable review on trustpilot[removed by editor]. Unfortunately, this looks dishonest or deceptive as it's a bit too close to "buying" a review, so I went to Trustpilot and raised my objections. Steamcarddelivery's response was to attempt to get Trustpilot to remove my review because I didn't buy their product. They've also routinely used this tactic against others... of eight negative reviews, seven magically vanished. If I want a steampowered[removed by editor] card, I shall buy one from a local bricks-and-mortar vendor; that has its own issues (as sometimes crooks tamper with cards and put them back on the display) but at least I'd have some recourse locally if anything goes wrong. With a faceless website? I have no idea who these people are, and can't rely on online reviews to assess their credibility if that process is being manipulated in this manner.
There appear to be some serious copyright issues with this site.
Many of the projects hosted here (Lostpedia, Gamewikis, Memory Alpha) appear to be under some sort of non-commercial Creative Commons licence. Invariably, those projects started as independents, until someone (usually one of the founders) sold the underlying domain name to Wikia (now FANDOM) - often over the community's objections. These projects mostly date to 2004-05. Wikia attempted to contract itself out of the "non-commercial" terms of the CC-NC licences in 2012... but that's too little, too late. Because of the way wiki works, every post to an existing page (and every translation of an existing page) creates a derivative work based on the previous version... and that derivative work must be subject to the non-commercial terms of the original. As such, this site looks to be violating copyright by using non-commercially licenced content and displaying intrusive commercial display advertisements against that content. Sadly, the cost of lawyers to get the infringing content shut down would be prohibitive. I've tried. In theory, there's also the right of the individual contributors to take their content and go elsewhere... but that gets hit with search engine duplicate content penalties. Wikia/FANDOM knows this. Pretty much the only way to win is not to play.
These people routinely remove valid reviews because their funding is not from consumers but from the same vendors who are being "reviewed".
I'd attempted to review a website "steamcarddelivery[removed by editor]" here, and gave them one star because of a questionable business practice - steamcarddelivery was attempting to "buy" favourable reviews on trustpilot[removed by editor] by offering a $3 discount in return for a review. This offer was sent in bulk e-mail to everyone who registers on the steamcarddelivery site. Steamcarddelivery retaliated by claiming to Trustpilot that I was not a buyer of their product and that this somehow made my review "fake". Upon further examination, Steamcarddelivery is doing this to everyone who leaves them a negative Trustpilot review: "Steamcarddelivery's reason for reporting: Please verify this review as this customer has not ordered from us" and Trustpilot is responding by blindly removing valid reviews. There is a link buried midway down the right-hand side of the page for each "reviewed" company which hides some interesting stats: Out of 17 recent reviews of Steamcarddelivery on Trustpilot, eight were negative and seven of them were removed by Trustpilot for no better reason than that Steamcarddelivery asked them to do so. That makes Trustpilot worse than useless.
