You have a right to say no to them and tell them to **bleep** off. it's your money, your rules. If you find someone is constantly begging you for money, say no to them. If they persist, warn them that you will report them for harrassment. If they cease to get that throught their heads, then report them for real and do your best to avoid them. If you can't avoid them, ignore them and report them for harrassment if they continue. If you have them in your BL, delete them. You aren't worth their time (or they're not from L'Oréal)
I understand why you would cling on to your guild as I cling on to Angels as well. But there is one thing I think that you should do. As talking buddies and guildies is fun, finding new friends is even more fun. Forging new bonds. That is what makes us human. Have nice chats with people in henny or in the forums. I did that and I met one of my good friends whom I'm still in contact with despite the fact she left maple a few months ago. Well, I did sort of transform into a huski, run into the sink care center she was in and started to.....um........yeah......you know......to her avatar's leg.........um.......ANYWAY! My advise is to say a simple "no" to those beggers of yours and try making new friends by simple talking to some people who you might want to befriend. Hell! you can even befriend me XD
