A few swipes into the popular dating app Bumble, and the diversity of interests is obvious: Users post photos of themselves swinging from trapezes, playing French horns, posing with freshly caught fish and, occasionally, brandishing a handgun or aiming a semiautomatic rifle.

But following a string of mass shootings and nationwide calls for gun control in recent weeks, Bumble is setting plans in motion to ban images of firearms for its nearly 30 million users.

The company joins a long list of businesses that have cut ties with the National Rifle Association or sought to clarify their relationship with the industry since a deadly shooting in Florida last month.

Some 5,000 moderators around the world will scour new and existing profiles and remove gun-related content, said Whitney Wolfe Herd, Bumble’s founder and chief executive. Bumble will not censor images that appear in users’ Instagram feeds, which can be integrated into Bumble profiles.
