RDM is a RuneScape player/security developer who runs and operates websites which prevent runescape phishing, hacking and malware.
RDM and his team consist of player moderators, anti abuse partners and youtube trusted flaggers, all working together as a collective to prevent phishing on Runescape.
His methods of anti-phishing mainly involve uploading counter phishing videos when a phishing video is uploaded on youtube. This gained attention from popular Runescape youtubers such as Silentc0re, ditterbitter etc. Silentc0re featured Asentrix in his promo "How much do phishers make"
RDM can often be found switching worlds rapidly on runescape looking for hijacked and phished accounts.
RDM alternates between the username "Phished" and "RDM".
