Noooooooo you don't need to purchase any vpns man, i actually had the exact same problem, but worse... just download tunnelbear vpn, google it. just when you bot make sure you turn it on, if u bot even for a second with the vpn switched off, it will trigger jagex's shit and fuck you in the ear. trust me, i've had it the worse! any more info about the vpn;tunnelbear , shoot me a pm
