RPGs and roleplay sites overall generally are discovered word of mouth. For example there's iwakuroleplay that hosts group roleplays as well as private, one-on-one roleplays. They're not drawing based and are heavily focused on literate writing. I only found them due to someone in the Wattpad roleplay scene back in 2014 (?) linking me to it as they were moving roleplay sites. I absolutely adore that site because of the safe-guarding of both adults and minors, and the ease of use.
There's also Artanis but I'm not sure how active it is. I signed up a few days ago and I'm still working on my character.
