There is perfectly benign interpretation of this expressing the things from which he derives pleasure. The most plausible and available interpretation of "pleasure card" is a dad joke level word play on "business card", especially when considering his role in de-commercializing software.

Talking to women isn't a crime. If he didn't take no for an answer or asked women out in inappropriate circumstances, that's a problem; but we have no accounts of him doing that. All we have here is an Nth hand story [3] in which he supposedly left a conference with a woman (singular, you made it plural.) and then gave her his card. If we choose to imagine there was romantic intent, a) there's no suggestion he coerced her into leaving and b) he took pains to respect the conference's CoC. Even this extremely reaching accusation has zero implication that he disrespected an individual's volition. Sage Sharp's indictment that he "skirted around the conference's CoC" is bizarre unless the real intent is that men like Stallman should be closeted heterosexuals.

There are numerous aspects to all this hand wringing about his cards and interest in meeting women that one has to choose to view through a prurient lens to make it sexual. Even then, it's only problematic to a puritanical world view in which it's wrong for people to be sexual beings and individuals are dispossessed of their self-determination.
