Recruiters are quite common in cities with a lot of jobs going, and industries with a lot of demand.
In terms of bad recruiters: A recruitment agency will often get a fee of ~20% of an employee's first year's salary - meaning they are extremely motivated.
That high level of motivation has some benefits - for candidates, they'll happily take care of any BS like entering your details into different companies' candidate tracking systems, writing carefully customised cover letters for each job, following up with companies after interviews and so on. And for employers, recruiters will deal with grubby business like cold-calling candidates and will often have access to more candidates.
It also has a bunch of disadvantages - recruiters will happily post fake high-salary jobs to gather resumes, add lies to candidates' resumes, help candidates cheat on work-sample tests, send generous 'gifts' to hiring teams that take their candidates, apply high-pressure sales tactics to wavering candidates, call candidates they placed after a year or two and encourage them to move jobs, and copy the contact database any time they leave a job.
