In a case like that, where a coward hides behind the mask of an anonymous troll, a little root work can protect your psyche from further attack.
The best and easiest way to take care of this kind of thing is to put a pinch of salt in all the corners of your home (for general protection) and to keep a little open basin of salt near your work space/computer to specifically keep harm at bay. This is an updating of an old root trick to avert the evil eye. Not only is it effective, but glancing now and then at your little basin of salt helps you stay calm and psychically focused which in turn makes you more able to ignore the trolls.
Another helpful and easy to initiate working is to have a picture of someone you admire and feel is able to protect you on or near your computer. Your Dad, your husband, you dog, or a favorite Saint are just a few options. I have a picture of an equestrian statue of St. Jeanne d’Arc on my computer to help me out in time of need.
Keep it simple is a good mantra regardless of the task at hand. Stay safe and bonne chance ~
