Hmm, to me it’s kind of right there in the first paragraph. I’m not defending Sheen in general.

Sometimes they praise each other’s parenting to the press. Other times they accuse each other of sending vile e-mails and indulging in underage porn.

…
April 19, 2006: Richards files for divorce from Sheen, alleging he’s unstable, violent, addicted to gambling and prostitutes, and visits pornographic Web sites featuring young men and girls who appear to be underage. She also claims Sheen assaulted her and threatened her life during a 2005 incident at her Los Angeles home.

…
the Sheen-Richards headlines have run the gamut from sad to malicious to just plain weird. Sheen accused Richards of asking for his sperm; Richards called said sperm “prostitute-tranny infested.” Sheen claimed Richards calls him for no reason; Richards said Sheen sent her a text message telling her to “get cancer” and “rot in hell.”
