Unfortunately, there are crazy people out there with nothing better to do than cause trouble. When one of these crazies threaten to troll you and destroy your business you need to take action – fast. Even if you have done absolutely nothing to deserve such harassment it is still not good for business. Therefore, you need to have a crisis management plan in place.
Firstly, block that person as soon as possible. If you are away from the office you can do this on your phone. This must be done immediately to contain the problem. A lot of damage can be done in a short space of time.
Secondly, turn off the setting that allows people to publish on your page. This can be a temporary measure until the issue is resolved and things settle.
Lastly, turn off your review tab on your page. This cannot be done on your phone, you will need to do this on a computer. This is why it is a good idea to have another trusted person as an administrator on your page so that if things go bad while you are out then you can call them to and ask them to do the above three things.
Be sure to have an action plan in place and be ready for any crazies that come your way.
