What does the message "This outsourcer has been banned from posting jobs at ProZ.com" mean?

As per ProZ.com termination policy, if a total of two non-payment complaints regarding a single outsourcer have been received from unrelated sources, the issue will be brought to ProZ.com staff for review. At its sole discretion, ProZ.com staff may then choose to suspend or revoke the outsourcer's right to use ProZ.com. This note refers to that suspension.
