Since long I’m getting the Ketto advertisements everywhere. Even while browsing OTF, these ads are showing 2-3 times in a single page!
Looks like you are a victim of targeted advertising. This usually happens if you have searched/visited ketto website often, or donated/shared one of their campaigns. It is also based on your watch history on YouTube, Facebook and other social sites. The ads which you skip and the ones you fully watch, all matters.
If you have consented to any user experience program, opt out of them. Clear your browser cache, cookies, site settings completely. Clear the temp folders on your computer. If they are served thru Google ads, you can report not to show such ads. Clear/reset ad preferences from Google settings as said by
@Abhinav842 bro.
Also ketto earlier had a Google form to opt out of their targeted ads. It has been recently taken down for some reason. You can try to contact the support team of ketto to mark you out of their targeted ads. Although there's no guarantee they would do that, you can give it a go. These are some basic steps to try to avoid those ads.
Ofcourse the simplest and easier way is to install a adblocker. But, as
@dud3rulz bro said don't hurt your favourite sites. We are also serving ads, because of which we could run this site on a powerful and expensive server for a smooth experience for members. Having said that, it's not within the rules as mentioned in our rules page to discuss about ad blocking as it would be like digging own grave. So I am closing this thread, as you have already got your answers. Thank you.
