Do proxys cause any damage?
No it cannot cause damage considering the IP packets aren’t sent to the web server from your schools computer, they are sent from the proxy. What that means is all the HTTP requests that are being sent are not being sent or determined from the schools IP address, they are all coming from the Proxy. All a proxy is, is a regenerated IP address with a port. The port is used for communication, and the IP is used for sending the packets and HTTP requests. A proxy cannot cause crashing.
