You guys asked for it so I guess I deliver it.
Intro
Keep in mind there is no way to really remove the chances of getting a weird girl with online dating. So don't be thinking is this some holy grail or something to never run into a weird girl from online dating. But there are ways tho to reduce the chances of getting a weird girl from online dating tho. A lot of this stuff I picked up from talking to people online as well in real life and used it to my advantage. Anyway time for the good stuff
The Method
In short all you are going to be doing is profiling the profile/girl. Thats it. There is a lot you can tell from a persons profile some of which is "verbal" or said by text, some of it is not "verbal" but is said in the underlining text, and lastly there is the visual or the pictures. All this info can possible tell you if the girl is weird or not.
- Pics/Visual
Weird girls more often than not are going to have a "something not right here" vibe in their pics. There is no defined thing to look for but for that vib. It could be how they pose for their pics to the context of the pics to the overall feel of the pic. Saying that there may be some indicators you can look for but in no way guarantee the girl is weird. One is their eyes do they have puppy or desperate looking eyes. Another thing to look for do they show a lot of cleavage but in a non sexual way but in a desperate or way obvious way? Another thing is do they have a downgraded look about them? Weird girls tend to not blend in with society in general and such their fashion sense shows this.
- Visual/Text
This one can give a lot of info depend on the girls profile. One of the biggies here is how is the girls sentence structure. This is key. Is it neat and proper or is it in shambles? Another thing to look for is context, what do they say? Do they seem to cover up an insecurity or do they show a one by saying it? Weird girls are more than likely to be insecure in themselves than normal girls will be. Another thing to look for in text is how do they reply to your messages. There is a good chance they be using text/internet speak/slang but in a youngist manner. Another is the length of the profile, if its really short or really long there is a chance the girl is weird.
- Non visual
This is basically read between the lines and where most of the "magic" happens to tell if a girl is weird or not. As this entails feeling the girl's vibe and how she comes across in her profile. Some things to look is does she seem defensive or guarded when you ask her personal questions, this means does she give you limited to no info in her reply or questions your wanting to know.
Conclusion
This is not an exact science at all. There is no fool proof way to tell how weird a girl will be. This is like learning to read body language. You are going to have to learn how to read the profile to tell if the girl is weird or not.
