She had a twitter account where she was teasing raceplay a while ago. If you wanted anything with slurs you had to pay for it so i cant say for sure if it actually exists out there somewhere. The @ was @racist_chery or something like that. It got suspended pretty quickly though so you cant find it anymore
I have this brief stream snippet I guess. No slur usage incase you're into hard RP, but I'm not, so idrc.
I have a vague memory of her making a similar "BBC" quote in one of her 2+ year older streams, but didn't save it at the time. It probably still exists, but it's a needle in a haystack situation. I know nothing of the supposed twitter account mentioned above though, but I doubt it was actually her.
Haven't kept an eye on her streams lately. But at a quick glance she still uses it and or one of her other differently sized black dildo's on fair occasion. She might have used them more frequently at some point but I can't say for sure. I don't see much of a reason for her to stop using them altogether though.
