Main problem in Linkedin is recruiters approaching you without telling the company name and specific position within the company. Like why would I even bother responding if I can't lookup anything about the company?
Trust me, I have a vested interest in applying through the recruiter because I know the recruiter will poke the company when I need him to. So I won't just apply to the company behind your back, but don't waste my time please.
I was once on a call with a recruiter - the company seemed interesting - asking what positions they are looking people for, only to be met with question what can I do.
I mentioned software development and some project management things, but we kind of ended up talking in loops. It was difficult to tell what I can do when they didn't seem to know what they were looking for or had available.
Conspiracy theory time: I have been applying to a lot of companies on LinkedIn. I noticed something strange. Many companies would have 30-40K followers but just 1-2 employees. They have tonnes of openings for a variety of roles. You can do the easy apply. I feel they are just harvesting your CV/Resumé and selling it.
I've seen something similar wrt founders and startup bros. It's kinda funny when some seed/Series A/B startup founder has like 30-40k followers. Meanwhile, even behemoths like Joel Spolsky and Michael Seibel have "only" 5-15k followers.
Your solution requires manual entry, this is a right click away (most people rather not spend time fiddling with uBO), also that solution relays on css selectors not changing in the near future, this extension keeps working regardless.
It adds "display: none" so it doesn't delete DOM nodes so its not likely to mess with pagination, but of course JavaScript can do anything (e.g. measure the rendered height) so it's possible that it messes with some layouts; I remembered trying it on facebook and it went awry, I had to undo it (in the options page of the extension you can see the full list of your filters and just hit "delete" on one)
There's a notorious job agency in London that spams users inboxes in what I suspect is attempt with fake jobs in order to collect CVs. I don't think this is exclusive this particular agency but still pretty rare.
With the advent of GDPR it's a sketchy way of getting around rention laws or advertising for months to do more of the same.
LinkedIn needs a 'block this agency/company' feature but I think that would impact it's bottom line.
