Skydiver, I feel your pain. We have the identical problem.
I was all set to post a workaround not requiring upgrading: it involves disabling REPORT POST completely, but rejiggering the UBBFriend feature as a means for registered members to still report spam postings.
Unfortunately...
Even after disabling REPORT POST, we are STILL getting spam. If I can get the REPORT POST spam to stop (even after disabling that option), I will gladly post exactly what our workaround was. But as it stands at least for us, disabling REPORT POST has NOT stopped the REPORT POST spam.
