I'm not looking for a Dom so the problem of meeting an asshole isn't that big. And playing with assholes (btw, the correct term and spelling is "Arschloch") can be fun too
I'm not sure there are hard signs for telling immediately if someone is an asshole. Communication via chat and messages leave ample room for misunderstandings, at least in the beginning. They shouldn't persist, though.
I think the best thing to do is not to rush it and listen to your gut feeling. Time will separate the assholes from the gems.
Oh my god. Just hate them. And my friggin' guilt-complex makes me writing them an elaborate apology why i rejected their friendship request when i just shouldn't give a damn about it.
