Sorry to hear this news Speffects. RS did it to me, Bangle, Hooters, Mosule, Misrule and Moogarm. I was in shock for a week after losing 1,900 links, 500k premium points and not having premium access for the first time since 2005.
RS has the legal right to close accounts for abuse, which probably is 95% of all Premium Accounts with uploads. They are closing accounts with the most premium points and uploads; probably as a cost-cutting measure. They are arrogant assholes.
