I received your PM jjj, and just to keep things transparent on the site, as we always do, I'll post back here on the forums for all to see.
The first URL you mentioned in the PM was soft.foxtab.com, although that site has a rather favorable reputation both in WOT and SiteAdvisor and on many other sites across the net, so I'm guessing it's really the appearance of the ad which is questionable.
Hastily, I'd probably agree that it does give off the impression of a download button and as such some would be likely to hit it thinking they were downloading from our site although as I say above the issue with this is there are most probably many other advertisements like this coming from Google Adsense and banning them all would be somewhat impractical. I also think our download button is one of the most obvious download buttons on a download site, placed right at the top of the listing whereas most others are hidden at the bottom or along the side and usually wrapped with other ads to purposely mislead people into clicking an ad instead of the download button itself.
As it is just now, we have many people on the site who will use ad-blockers and all manner of other tools to suppress ads from being shown on our site and if we started removing ads because they give off the appearance of a download button then we're just removing one ad to be replaced by another, which may be along the same lines. Eventually, if we continue to ban those ads like this we'd be left with virtually no ads to serve, and the future of the site would be in question as what little revenue we have coming in at the moment from these ads still helps towards the costs of the site. Instead, I'd reiterate what I said above, and that is the removal of all ads is automatic for anyone with a post count of 10 or more and I really do think it's a small price to pay.
As for the other URL (http://www.magicaudiotools.com/free-m4a-to-mp3-converter
) you mention that ordering anything from them takes us to plimus.com. This is where it becomes a little tricky, but I'll try to explain the best I can. plimus.com is merely an 'agent' for software developers - when a developer wants to sell software, they will use someone like plimus.com to process their orders for them, they take a little cut of the order and pass the rest of the revenue along to the developer. If a developer releases software which is bad, it's often the case that the user believes plimus.com to be the culprit (as it was them that 'processed' the order) and will then rate their website negatively, which is probably why those guys and other agents such as shareit or regnow have negative ratings in WOT, etc. It's not necessarily those guys who are at fault, it's the unscrupulous developers who are to blame most often. As for those 'agents' ripping people off by charging them more than they should, well that's something I can't comment on unfortunately as that's going into the whole world of shareware and payware which is something I know very little about and have no involvement in as we're a freeware site but again, if we start removing good developer sites because they use an agent to process paid versions of their software who is rated negatively (and most times incorrectly) we're just opening a whole can of worms for ourselves I think.
Finally, you mention a whois check on magicaudiotools.com leads to PrivacyProtect.org which ensures anonymity for domain name, believe it or not we also use that service as without it my personal home address, telephone number and other private details would be available for anyone to see online and I would be subject to many annoying telephone calls and spam emails all wanting to give me a great deal on time-shares or something else ridiculous - it's a sad fact today that a lot of webmasters today have to use services like this to protect their personal details, as there is always someone out there waiting to pounce and use them in some way.
I do appreciate your concerns and thank you for actually taking the time you do to bring these things to my attention, but in circumstances like this it's an impossible task and one which would be never ending. Until we reach the day where we are able to remove all ads from the site, vigilance is needed and I'd encourage all users to use their own discretion but where any ad takes us to a badly rated website it's an open and shut case for us, that URL will be banned outright
