Why does /r/Seduction not support guys to tell girls they like them?

I mean, the only way I see that it can be bad is if you meet a girl, become friends with her, ended up in the friend zone and let her treat you really bad (for a long time), then tell her you like her.

I have noticed a paradigm that if I don't tell a girl that I find her attractive or that I like her within a short period of meeting her, or my second run in with her, I won't go on a date with her, unless she is really interested in me, and it's blatantly obvious.

I think it works for me, because I don't hide my interest and I am not ashamed of it. I usually look her in the eyes, have a big smile, and say it in a flirty tone that I like her a lot, she's gorgeous and that I want to go on a date with her. Before doing this, I usually kino her and have a flirty convo with her to gauge her interest though. I mean, I don't have a 100% success rate, but I doubt that it's for the reason that I told her I liked her, and probably because they weren't interested in me in the first place.

What's /r/seduction opinion on this?
