I'd like to inform you all about what was going on with me. I own HostBaker.Net
I provide free hosting but can also arrange paid plans. One person requested me to arrange a paid plan for him - I did arranged it. He paid me and I made his account.
Some hours later - I checked his account to ensure he is not hosting anything illegal and found Pirated software downloads. I just suspended his account within a few minutes and emailed him about the condition. He requested me to give him a 2nd chance but I declined to do so. I asked him to pay $5 unsuspension fee. He just replied that he will take revenge.
Now on 23 feb 2010 I got email from him in which he informed me that he had started his own hosting company hostbaker.com and this will really effect hostbaker.net business.
Now I contacted his domain registerar but they said that they will only listen to me if I have trademark of the name "HostBaker". I don't have trademarks.
Please tell me what should I do prevent my business from being affected.
Your help will be very appreciated.
