If you ask penny to recruit her, the first time she says no and you have to go through her whole quest line, which is reflected in the log. However, if you just give her throb, all the way, and then ask to recruit (a second time) you bypass here whole mission on the basis she isn't really working anyways, and you can recruit her as a cam whore. However this does not update in the log, it stays on "Status: Asked Penny, She refused, Perhaps you should get to know her better?".
On a similar note, after making penny bimbo her talk options displays her sex options, so you can't for example give her a horse cock.
