It's not that people have provided false information, but the system allows people to use the 60 days provided for them to send their application post-ITA as included in the calculation for the work experience, i.e. 3 years to get 50 points.
However, many of them are scared that because on the date of the draw, they didn't have 3 years already completed, their application may be rejected.
I wish they would just follow the advice to include the period in their days to apply post-ITA. So let's say you need one more month to reach 3 years of experience, then send your application at least 30 days after receiving the ITA to cover this period.
What sucks is when such people decline their ITAs, they in order to wait for the next round of invitation. They're basically wasting an ITA that could have gone to someone else.
