It is allowed to some degree, way stricter censorship being applied if you want to stay on the mobile app
Here's an example from my comic of how much is allowed on browser vs on the app (I've post them as separate comics)
General rule being
browser - censor the genitals, mosaic is ok
app - either cut out or hide behind opaque stuff genitals and nipples (during sexual context, I think nipples are fine if character's just standing around)
If you want to publish your work without any censorship then the options I know of are comic fury, flowfo, patreon, subscriberstar (those especially if you wish to put your stuff behind a paywall) and itch.io once you've got enough to collect it into a pdf file
oh, and globalcomix lets you get away with similair level of censorship as tapas browser version
