I just finished 墙 stalking BlindBandit92.(sorry bro)
Annd I usually do 更多 than 墙 stalk, i also check their photo's (only if they have pictures of themselves) then their 链接 (only if if's to someones profile) then I do the same to their friends.
there r threee guys i have in mind that probably stalk my walls, they used to send me messages asking me if i wanted to test their lips and 破烂, 垃圾 like. i dont really stalk peoples walls, i just look at 随意 people that i just met's 个人资料 once 或者 twice. :|
