If you are being subjected to any form of long term harassment, intimidation, vandalism, racism stalking, verbal abuse, or a targeted campaign of malicious gossip, the following information might be helpful:
Some groups of people seem to be more at risk from this than others. The person who is responsible for this has strong connections with a group of paedophiles, so if you have a family, please take the following security measures.
1) Buy a cheap used laptop / desktop – almost any old computer will do, so there is no need to pay a lot. Use this to type letters, store your family photographs and other personal stuff. Keep all documents with your home address, location of your children's school etc. on this machine. Never use it on the internet.
2) Transfer all the private data from your internet computer to the used laptop / desktop and re-format the hard drive of the internet computer.
3) Install some decent security software on the internet computer (a firewall which 'stealths' your IP address would ideal).
Hope this helps.
