I'm finding that if our users have the Pinterest browser plugin installed they end up with (sometimes a lot) of additional code added to their HTML content they are working on.  The extra content looks like this:

<p><span style="line-height: 1.5;"><a href="//www.pinterest.com/pin/create/extension/" style="height: 20px; width: 40px; position: absolute; opacity: 0.85; z-index: 8675309; display: none; cursor: pointer; border: medium none; background-color: transparent; background-image: url(&quot;data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACgAAAAUCAYAAAD/Rn+7AAADU0lEQVR42s2WXUhTYRjHz0VEVPRFUGmtVEaFUZFhHxBhsotCU5JwBWEf1EWEEVHQx4UfFWYkFa2biPJiXbUta33OXFtuUXMzJ4bK3Nqay7m5NeZq6h/tPQ+xU20zugjOxR/+7/O8539+5znnwMtNTExwJtMb3L/fiLv3botCSmUjeCaejTOb39AiFothfHxcFIrHY8RksZjBsckJcOIRMfFsHD/SsbExUYpnI8DR0dGUGjSb0byhEJp5Uqg5CTSzc2CQleJbMEj9/ywBcGRkJEk9DQqouEVQT1sK444yWI9UonmTjGqauVLEIlHa9x8lAMbj8SSpp0rwKGMVvg8P46vbg0C7na8z8JsMcgHe7jlEa+edRhiLy8n/TUMfu6EvLElk+U0WtGwrTrdfAGQf5J8iiK4LVzDU28t8JtMSocf8E+l68myaNFXm/6rXslLK7ay5TOunuRvZWpJuvwAYjUaTpOIWoquuAZ219RTaxKYp9BbjycoN5FvL9qH9TBX5rvoGdJythvXYSTxdtRnWylO/ZdqrLsGwszzhWQ593z2KlAwCYCQSSZJ6ehZ0W7bD9VBLgN0NCqr3qR7R2rBrL3pu3Sb/7nDlz2uy6cG0OXk0GTbZXzNp8trsPAQdTj6frlWzN2DcXZGKQQAMh8NJ6rpyHe+PnkCr/CAFdZyvpfpjuvkifLF9wIt1Wwlo0OHie1RvWrKa93RjzfzliTzPKz3ltB0/Tevmwp14wGUgHAzSOoUEwFAolFaaBSuhnslPRkJexUJtZ6v5HtUeLswl33n1BgEY5fvhs9sJ3FAiT+QYyyvoAQJuD0KBAFRTJNAuz5/s3gJgMBhMJwrVFRThM5tY5zUF/A4X1f2fvQTRLCuBreoim0YmAbqNJryvPEXeeq46kaNdkQ/1HCncbJKPs9ZSv2VHGfWsZ2hfkhKAfr8/pdxWKx4wwD69PmVfNSOL+lr2w+gYqHpWDtXt1xQ8AMlWU0e1lqLd/APRHoP8AJqWrQG9gYxcPMsvSJUvAA4MDKTUJ7MZLaVy8v+qT21tcDx/OemePr0RTkNrur4A6PP5xCgBsL+/X4wiQDpuuVxOeL1eMYmYeDY6sOp0z+B0OuHxeEQhxkJMFosJiSO/UinOI/8Pc+l7KKArAT8AAAAASUVORK5CYII=&quot;); top: 1909px; left: 432px;"></a></span><br></p><p></p>

 

 and this can be repeated, 2, 3, 15+ times depending on how many times it's edited.  There isn't any way that we can prevent users from installing this plugin, and there isn't any way that we can prevent users from using the editor if they have this plugin, so we have to figure out a way to work around it.  Ideally i guess we'd need some kind of filter to auto remove this, but i guess we'd need something server side as well.  I'm going to take a stab at it, but i was wondering if this has come up before.  i'm surprised that i didn't see any mention of this anywhere else in the forum.

Thanks!

Hello Mark,

Indeed, no body can prevent users to install such a plugin along with RadEditor. Although, programmatically there is no approach to capture whether such a content is added by the user or a plugin, and thus, it would quite a harmful measure to strip it out without the knowledge of the user.

As of now, nobody have reported such issue and I am not aware of a read-to-use solution.

However, your assumptions is correct, you can implement a custom filter (http://docs.telerik.com/devtools/aspnet-ajax/controls/editor/managing-content/content-filters#implementing-a-custom-filter) that to strip out the additional content added by Pinterest plugin.
