Most likely, yes. This is very deceptive behavior. The person behind the account is being rejected, not his imaginary identities nor tens nor hundreds of identities. If one, despite the rejection, tries to infiltrate the service provider again with another mask then they are actively trying to get around the rejection - thus deception, thus untrustworthy. Does this make sense?
Yes. I mean I can follow your reasoning. I wouldn't tag for it if they were never in the campaign at the same time and even then I'd still defer to the campaign manager to determine if they were deceived. For all I know managers can make any exceptions to the rules.
