I've certainly become friends with a number of girls I met through dating sites like tinder and OK Cupid, but in the vast majority of cases, those began with actual dates with romantic intentions. When it became clear there was no romantic potential, but we still wanted to be friends, we pursued friendship only. I'm also strictly friends with a number of people I used to date, which I know people sometimes find weird.
It's rare that I'd pursue strict friendship from the outset, but on one occasion, I matched with a girl on tinder with no profile photos but who had an interesting bio. I learned that she was just looking for friends, but I found her interesting enough that I was okay with just pursuing that. I never saw a photo of her before we met, although I did speak with her on the phone to make sure she wasn't some psycho. We've been friends for over a year and there is no attraction between us. She considers herself to be borderline asexual, although I frequently make fun of her for using dating sites like OK Cupid and tinder to find friends or conduct 'social experiments'.
These things are definitely not the norm I feel. I guess if your bio on dating sites is explicitly written to indicate that you want friends only, it might be worth a shot, but I'd imagine you still get a bunch of thirsty dudes promising to cure you of your asexuality by showing you what 'romance' is all about.
