Angel1230 has been punished for scamming you, though unfortunately I can not help you get your 3 euros back as you should have done an admin trade. I suggest making a support ticket so a higher staff member may be able to help you.
I believe infinitepvp has made a support ticket regarding this, but for your own sake you should also make a support ticket explaining what happened. aXed or a higher staff member will deal with your issue accordingly.
Mind your own business? Don't be so toxic, you would be muted either way even if he reported Menno along with you. If you want Menno to be muted, go make a separate report please instead of being salty over your own mistake.
Thanks for the report, but unfortunately we don't punish for players admitting to hacking; more proof is needed. For sure if you see an admin in game though you can let them know with /helpop or /msg to check him out.
