Rape threats were made towards her daughter, death threats towards her son, and fans of Pernice told her they hoped she would die of cancer, Abbington said.
Abbington said she hoped that Strictly would go on as “a beautiful British institution”, but said she deserved an apology from the BBC.
“I’d like an apology and I’d like this not to happen to people working in that corporation again. I’d like women to be listened to and heard and taken seriously.”
The BBC said in a statement: “Anyone involved in a complaint has a right to confidentiality and fair process and therefore it would be inappropriate to comment further on individuals.
“However, when issues are raised with us we always take them extremely seriously and have appropriate processes in place to manage this.”
Katya Virshilas, a former professional dancer, told Sky News she believed bosses on the show sometimes prioritised dancers’ looks over their teaching ability.
Virshilas, who appeared in three seasons of the show between 2009 and 2011, claimed producers “know everything” as you are “living under a glass house” and said her time on Strictly was “one of the hardest and toughest times of my life”.
She questioned whether bosses pick “a young, talented dancer for their looks and how they do tricks, and not so much caring about [if they are] actually able to teach?”
She added that while Strictly is a rewarding experience that had “done so much” for dancing, she had “experienced bullying from other pros towards other pros”.
“We are dancers. We’re in that environment … dancers can be brutal towards each other, but I guess we’re used to it,” she told the broadcaster.
