its an extension as i see. You told, you can see which sites your extension is used on. If its a porn site, make it unattractive to use your extension on such sites or accept/use that knowledge. one way of making it unattractive is to put a captcha or some distracting something before the text is put into the input-field. Or you accept that a multipurpose tool is used multipurpose :)
