Twitter founder and CEO Jack Dorsey announced abruptly — though the timing was certainly not accidental — that the platform would soon disallow any and all political advertising. This is the right thing to do, but it’s also going to be hard as hell for a lot of reasons. As usual in tech and politics, no good deed goes unpunished.

Malicious actors state-sponsored and otherwise have and will continue to attempt to influence the outcome of U.S. elections via online means including political ads and astroturfing. Banning such ads outright is an obvious, if rather heavy-handed solution — but given that online platforms seem to have made little progress on more targeted measures, it’s the only one realistically available to deploy now.
