Your average Party HQ is underfunded and understaffed and largely employs people who view their jobs as a stepping stone to something actually important and who certainly aren't paid well or granted sufficient job security to re-assess that view. Your average local party is run by a small group of pensioners who probably need assistance to turn a laptop on, let alone run even a basic search.
What's stopping parties recruiting unpaid/lowly paid teenagers with tech skills and ideological devotion to do that instead?
