I think most of us can agree that it isn't the best use of the site, but unless we take a pretty narrow and bizarre view of what "social" means I'm not sure how we can say that.
There is nothing in the terms and rules here prohibiting such activity, and women sure do contact guys here with such aims as I found to my own chagrin. Apparently the site is notorious for such instances, though many prefer to sweep it under the rug and pretend that it doesn't go on except at the point in time when it boils over.
I'm not sure why honest actors couldn't engage in this without trouble, but it would be healthiest for them to take it far away from here as soon as possible. Tolerance seems low and judgement levels very high. Toxicity and jealousy lie very near the surface,
Meanwhile, there is a prohibition here about racism, yet I've seen it over and over here and even called it out a time or two. "No politics" is a rule, yet thread after thread here touts a very hot apartheid situation in the world.
Sour pickles live in glass houses, and should know better than to cast stones. A little tolerance hardly seems unwarranted.
