So I've done a bit of investigating:
[SYM3OL]^VCPR_850^'s IP address on the 4th of November, ~ 15:23: 182.181.247.83
[SYM3OL]^VCPR_850^'s IP address on the 4th of November, ~ 14:29: 41.196.244.33
Nearly the same goes for the other account in question (VCPR_850).
Vicecity.'s IP address on the 4th of November, ~ 15:25: 182.181.247.83
Holden's IP address on the 4th of November, ~ 15:27: 182.181.247.83
Judging by the logs provided by krystianoo, which have greatly assisted in this investigation, it is reasonable to assume that Vicecity. / Holden has successfully scammed the author of this thread, resulting in the loss of (I quote) 380k worth of money and 2 cars.
The staff is not responsible for naivety, and so neither the money nor the cars will be refunded, consider this a lesson.
The staff is, however, responsible for taking action against rulebreakers, and action will be taken on two counts: advertising, and scamming/unauthorized access of player accounts, the latter being a high severity rule.
Vicecity. / Holden has been permanently banned from the server for breaking the aforementioned rules, and this ban is set to expire when hell freezes over.
