I play RS for a while. I couldn't bear those selfish, inconsiderate and unreasonable neighbors who keep asking for Parts; some of them sent food for a few times since beginning to be their neighbors then requested parts via different methods at later time and, some only want to get parts (never ever sent food and/or tipped at all). If writing on their walls to just let them know what I want and don't want...I got insulted, removed/blocked by them. Before they invited me or I added them, I'd already written on my wall very clearly what type of neighbors I'm looking for but very few could actually pay attention. Therefore, I had a lot of regrets after adding those people I mentioned above.
I really hope I/we (RS players) can be able to block Parts Requests or Parts Gifts in case again added a wrong neighbor one more time.
