To be fair, most employers include a lot of things in their job ads that shouldn't necessarily be taken literally or in the strictest sense possible. For example, a decent chunk of ads I've seen ask for a set of qualifications that would leave them with zero applicants if taken literally. I've also heard from multiple hiring managers and recruiters that "if you're not qualified but you really want to job, you should apply anyway".
Applying for a "full time" job, if you expect to be able to handle a "full time workload" is not a great stretch.
Also, as several other commenters have pointed out, employers routinely leave a lot of critical details out in the early stages — especially details that might make applicants not bother applying at all. Unless you're very clearly a rare exception to that norm (i.e. an applicant can tell that easily from the job ad) then it's a bit rich to expect applicants to lay everything on the table before you've even met.
