Those add-ons are something we have to live with. It's how the IMGBB site makes there money, and they won't change that. They don't even answer when emailed. As long as the content is clean no-body will take any action. Plus we also have the choice to remove the added link before we post. A consolation is that we are not alone. It's the same on all of the Probaords Forums, who are using the IMGBB.
