Well, I use a plugin which I load from wordpress.org. And I did noticed last week something strange happen on my site. There is a external CSS Code on all sites. I was sure I did not include it. So my first thought was: I got hacked!
If I looked in details, I saw this was from the Plugin. And the only chance to remove this, was to change the source code.
So, my question is, is this ok that a plugin include external sources?
and if, even if there is no choice to deactivate this?
I think there should be a clear definition about this, because external code could spy my visitors and I usually avoid this.
