According to Broadcast, Channel 5 has permanently suspended the service on the social networking site.
Facebook voting will not be available for next Monday's Big Brother final or the entire Celebrity Big Brother run which launches next Wednesday.
Richard Desmond's network faced criticism after complaints to Ofcom suggested that viewers were unable to access the Big Brother Facebook page for the 2011 final, but the broadcaster was cleared of any wrongdoing in March.
However, Channel 5 accepted that "exceptionally high traffic" meant that a few fans may have struggled to cast their votes after purchasing their credits.
The reality show became the first UK television programme to use Facebook Credits as a voting mechanic.
Big Brother's latest classic series concludes on Monday, August 13, with Celebrity Big Brother running from Wednesday, August 15 for 23 days.
