Woe betide you if you link with a recruitment agent because they will indiscriminately spam everyone who matches a keyword search. Repeatedly and often. These days I simple ignore all invites from agents and unlinked those that I made previously. If an agent is desperate to speak with me they can use one of their precious in-mails. That said, I've had these dummies send me an inmail telling me of "a role I may be interested in" without saying what the role is, whether it is permanent / contract, where it is, how much it pays, or anything else. I ignore those too.
Some sites and wifi hotspots double down on this annoyance by inflicting it on their mobile pages too. So you have to enter an email twice from a handset. And just in case that wasn't enough, they fail to specify the field is for email so the phone browser's autocorrect fucks it up as you type it.
Either the original actor dies, or wants to do other things, or is too expensive (especially for TV / videogame spinoffs), or takes the whole tickle-me-elmo a little too far. So sound-a-likes are hired.
Ultimately the application may end up an embedded device, where space is at a premium. In that instance I'll probably have to static link but it depends on licencing issues.
