I've experienced that too where a few recruiters bombard my inbox with low quality jobs ("Entry-level Java .NET developer needed immediately for six week contract in Frostbite Falls, MN!

Protip: Spammy recruiters hate it when you politely decline in response to a LinkedIn message because LinkedIn only charges them when someone replies.
