It's not illegal to open up a dispute with PayPal, it (could) be a violation of their terms of service that you agreed to on HostSkool which varies. However, PayPal disputes in general look bad on an account and may lead to their account being limited for a certain amount of time which may be the reason why they respond faster because I wouldn't doubt that they've been getting chargebacks with the amount of reports I see on SA-MP about the lack of response.
