Hosting is cheap and there is free hosting available if you don’t care about having a custom domain and have a limited audience. If your audience is big enough to go past that bandwidth you can probably monetize somehow and cover server costs easily, even if it’s just selling a few pieces of merch. My website is $80 a year with a custom domain and I get unlimited transfer/bandwidth. It’s shared hosting so over about 1k visitors per day means it’ll get slow but if you’re getting that kind of traffic you can probably sell more merch and get a vps

Use twitter/pixiv/ig for promotion but if you don’t do the above your locking out anyone who refuses to make account. All of them won’t let you look at more than 1-5 images before locking you out entirely with account nag screens that can’t be bypassed. Or just stay on those platforms, I don’t care, I’ll just never read your comic

Yeah like $10 a month for a comic.

No, it really, seriously, doesn’t. People that rely on social media are just lazy and ignorant.

And it gives you some degree of control over reposts and people stealing content. If your not on the platform you cant really contest claims against a video or post.

Plenty of ways to host for free, even with a custom domain. (Though the domain is $15 per year) Like GitHub. Or you can even just use Tumblr with a custom domain.
