About Sandra Staniszewska

Sandra (aka BadGirlSandra / Bad Girl Sandra / “Sandra od Denisa”) is a Warsaw, Poland-based influencer, model, social media personality, and adult content creator.

She gained wider visibility as the former partner of Denis Załęcki (“Bad Boy”), a known figure in Polish freak-fight/MMA circles. Earlier appearances included streams and content linked to figures like Josef Bratan. She debuted in the FAME MMA organization at FAME MMA 25 (5 April 2025) in an exhibition bout against Magdalena Łoskot; she lost by unanimous decision after three rounds. It was treated as a non-professional/exhibition fight.

She is active as an adult content creator, primarily on OnlyFans where her content is explicit and unfiltered, covering solo material, hardcore boy/girl and group scenes, interracial collaborations, and various fetishes/roleplay (e.g., JOI, domination, toys, etc.). She has publicly promoted collaborations and recruitment for adult productions. Some Polish gossip reporting has also linked her to phone-sex work alongside her online adult output. She maintains a strong presence promoting this side of her work on social media.

She has offered escort services. Polish media covered the appearance of escort ads featuring her name/image (“Bad Girl Sandra” / linked to her known persona and OnlyFans handle @badgirlsandra). One notable example was on a Polish escort site (Roksa.plus), listing her as a Warsaw-based escort with rates around 2,000 zł per hour (and higher for longer sessions or additional services like filming). The ad explicitly directed people to her OnlyFans for other content and referenced her influencer background.

Reporters and others reportedly called the number provided in such an ad, and Sandra herself answered, according to coverage from sites like BOOP.pl. Gossip and fight-sports outlets also noted circulating information that she was arranging paid meetings with men.
Earlier reports additionally linked her to phone-sex work (“dziewczyna na telefon”) alongside her adult video production. These details come primarily from Polish gossip/media coverage and public escort listings rather than formal statements from her. Her main public activity remains online adult content (OnlyFans and similar platforms with explicit videos), influencer work, and the brief FAME MMA appearance. Escort-related claims appear to stem from a period of heightened controversy around her personal life and content.
