Earlier quoted context omitted.
The H-1B lottery this year was riddled with fraud - so much so that USCIS will be conducting a second lottery soon - but it appears that there was no reduction in the numbers despite layoffs in certain industries.
Where is there opportunity for fraud in the H-1B system? Fake / Shell companies sponsoring workers?
Also, it is stupid to call H1B a high-skilled visa when you hand it out via lotteries. I wonder if people consider winning powerball as a skill?
But to answer your question, many people filed 10-20 applications each through fake companies to get H1B. The H1b acceptance rate was down to 13% and more than half the applications were filed by people with multiple applications.
