When commenting on someone's LJ, I try and remember that it's not my LJ; it's theirs, and they can say whatever they want there. I usually just pass on by if I disagree with them. Now, I sometimes will get a bit rough with another person who comments if they are shitty with the LJ owner!

No. I am far too impatient to even read an LJ through a translator app.

I've only had to delete I think two comments; both were complete trolls who were commenting on my appearance in my user pic. I banned them, too.
