Sure, do your research.
If you don't know a lot about them then I think it's smart to do a little research. Just need to be open-minded, not everything they put in there is real.
if the person your dating is on face , absolutely not , and then i wud be careful as people dont even post things honestly , just look here at ep , how many people are in the young group and really are adults , i think your quite wise for doing this
If that is all your doing then your not really checking at all!!!
In a word, yes.
