As I said, there are a lot of purchased accounts in the Philippine section. It's only a matter of time so that sooner or later they show themselves.
Buying accounts aren't prohibited but we must make sure that they will never abuse this, if these accounts were to be found on the same Campaign then tagged them.
Please remind me of at least one case when it was revealed that the account was purchased, and it was not marked with negative trust?
Therefore, yes, buying is not prohibited. But it is not welcome, and as a rule, a tag is always put on such accounts.
Participation or non-participation of purchased accounts in one subscription company is another story. Rather, it is closer to the multi-account rule.
