Hello, I copied the information below from BF4DB's banning policy.

Third-Party Sites: Evidence from other third-party sites may be presented, however it may not meet our standard of evidence required to issue a ban. In the event that the evidence submitted is a Punkbuster Violation streamed to another service, it may only be used as supplemental evidence unless the violation in question was issued prior to February 1st, 2018.

Am I to understand correctly that if a punkbuster violation was streamed to another service prior to February, 2018 that BF4DB will uphold that ban? I just want to clarify before I make a report. 

We dismiss PB violations after the cutoff date being 1st of February, 2018.
Used only as secondary evidence.
