No, he can't. He's pointing out that your "company," Vitor Services, bought hacked accounts in order to engage in mass thread spamming. The worst part is the people who hired you don't even realize the forum mechanics have changed and you're no longer bumping this thread to the top of the section each time you post in it.
I hope they and the rest of your clients are smart enough to fire you immediately, but I doubt that they are.
I think you are wrong because now it makes no sense to do it. and I think everyone understands that. So complaints about hacked accounts should be sent to moderators.
