I think you're fine.  As long as people try to keep their stats and skills in mind when posting I am not overly worried about it.  If a player calls for or makes a roll, I tend to base the reaction off that, otherwise I tend to base the reaction on what they have written.  Just something I thought I should point out.  I try to keep ability scores and all that in mind, but if you want a big change in demeanor or similar you should make a roll.
