yeah, i do. and i try and do it where it counts the most. rep values are different around DP. if i rep you here, the value is much lower then if i repped you in BST area. but i cannot do it unless its signed.
I usually do when the member is contributing to the topic and not just seeking for approval from others by giving reps away just like that. Like for example, when I see a post like "thanks" I do not consider giving reps back but when the case is someone approves and appreciates your thoughts and he/she dwells on the topic further more by giving his or her opinion then I will certainly give the rep back.
Not always. Some people who leave me green rep are doing so on the assumption I'll automatically return the favour. I am choosy about who I rep. You get a lot of rape requests?
yes i rep two types of people if i liked their post or any one give me +1 rep and signed with his name and i give -ve rep also i donot care if that -1 of my rep but i like to be effective
