Firstly like it has been prior stated, you need screenshot or video proof of what has happened and also use the template provided by Stratic.
Furthermore, it is your own fault and this warning is valid, if you click a taunt in the pointshop, you have the option to preview it which will play it to yourself as if you had used F7 with it equipped. Following on, you also have the option to redeem some of your points from a miss purchase or if you change your mind about it by clicking the item in your inventory and selecting the sell item option, this should give back around a third to two thirds of your points.
Newdude was entitled to issue the warning as the rules clearly state:
- Do not beg for points, constant begging will lead to a warning.
