That article is signed by 'Admin', and has no references whatsoever. It doesn't even detail which were the alleged collaborations. It's difficult to take it seriously, the same article states that Ernesto Guevara made a concentration camp for homosexual, which is not far from reality, but an anachronism and also it just uses that to blame on Simone to say shi sat next to him once. (PS. Said concentration camp was the Cuban solution implemented by Castro, without forced labour iirc, and it was the best solution they came up during the raise of HIV, meanwhile the rest of the world didn't do much better. Heck even today we reject their blood donation, I mean from homosexuals which is plain wrong.. anyway.. just wanted to challenge the credibility of your link. But I don't mean to say that socialist don't commit crimes and mistakes.. I 'd be happy to see sources on the accusations of the article, just that. Ah. Did I open a parenthesis somewhere? Ok)
