I disagree. I get 4 phone calls a day from recruiters trying to sell me "talent" for my startup. They refuse to get off the phone when I politely tell them we have a policy of not using recruiters, follow up by email, and then of course they call again next month. My phone going off causes a distraction, causing me to fall out of the zone and waste a few minutes as I try to figure out why they're calling and try to politely get them off the phone.
Really, they are absolute fuckers with no consideration for anyone but themselves, and going nuclear is long past due.
