Hello, my name is Ben and it is my pleasure to assist you with your question today.
What do you hope to achieve please?
Hello sorry I was offline by the time you had replied last night. I fully understand that reading untruthful comments about yourself on a public forum can be upsetting. Whilst you may approach he person who made the comments and ask them to edit or remove them, if they refuse to do so, it will not be easy to force this through. In reality you will only be able to do this if you were to get a court order that requires the site to remove the comment. This will not be easy or cheap and to be honest should only be used as a last resort if the comments are either causing you financial loss or have serious consequences like losing your job.
In the meantime you could consider approaching the person who made the comments and telling them that their comments are defamatory, asking them to remove them and advising them that failure to do so could lead to you taking legal action to resolve the issue. This should hopefully be sufficient to remove the comments without any legal action but if that fails then the only way to remove these would be by going to court and trying to get a court order to force their removal.
Please let me know if this has answered your original question or if you need me to clarify anything else for you in relation to this?
