Yeah like $10 a month for a comic.

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.

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

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

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.
