These types of services are commonly used for abusive editing and circumventing Wikipedia policies, so Wikipedia blocks them as apreventive measure — even if you personally haven't done anything wrong.
How to resolve this:
Note: These blocks are applied because of the configuration of your network or internet connection. They arenot applied as a result of your actions, nor are they applied in order to discourage you from editing Wikipedia. Wealways appreciate good-faith contributors to this project, and we want to help you with being able to edit Wikipedia again.
