I highly doubt it. She had...other issues with the fan base, mostly growing pains and people hating that she wasn't Rachel. Which she got used to over time. Tamara and Malcolm though seemed to play smaller and smaller roles in these videos over time though and she wasn't getting any younger. It's not surprising that she left and wanted to do something else. Sometimes people just decide it's time to do other things with their life. I don't think she was ever sexually harassed, at least in any serious way, and I'm pretty sure she had a boyfriend her entire tenure at CA.
