TBH if I was applying myself I'd be pretty tempted as usually its just a time suck.
Personally, if I suspect somebody is a liar or a cheater, I won't hire them. I build teams that are low on micromanagement and high on independence and trust. Somebody inclined toward fraud can be a big problem in a context like that, both because of the direct damage they do and because they lower ambient level of trust.
I recently had somebody apply for an internship claiming extensive iOS experience with a nice iOS project on GitHub. But the commit history was shallow, so I did some digging. Turns out it was a group project, and one of the other people did almost all the work.
That person was instantly dead to me. They surely got a job somewhere, but I feel sorry for their coworkers, who at best had to pick up a lot of slack, and at worst had to put up with a bunch of new rules and micromanagement because one employee couldn't be trusted.
