Someone changed my profile to say Warning: Trade with extreme caution!
It is okay to be careful when lending to me as long as I am new here. It is a little extreme to say "extreme caution". I am not a scammer or anything.
What can I do to change this?
First of all
read the rules well. Especially the ones involving money (and lending).
Then make another account. At least the one negative feedback I've checked is valid; you can google more about the negative feedback if you want to learn. Search for: negative feedback site:bitcointalk.org
Again, please read a little more before making the new account, since else you'll end up again with negative feedback sooner or later.
