My comic had mainly started on deviantART in September 2017 and then in 2018 I hosted it on Tapas, Webtoons, Smackjeeves and Comicfury.
Though mainly on twitter and insta, I advertise through tapas/webtoons since that's usually at most of what others use to read.
In fairness, it's just for other people to read who don't use the apps or prefer one comic host to the other .v.
