This LJ is semi friend-locked. I usually don't put under lock most of my posts especially those regarding icons and fanarts because I'm used to crosspost them in various communities. The posts that are most likely to be locked are the one of ranting, bitching and general personal issues.
When I get friended I usually friend back if I see we have interests in common, otherwise you're free to leave a comment in this post and let me know something about you and why you want to friend me.
