I can assure you that reviews are not being removed... intentionally. We do not do this!
What I need to investigate is where they are going. Please let me know the Link ID you reviewed so that I can search the database.
Also, please note that we are in the process of redoing the entire backend of HotScripts.com, with a release scheduled for first quarter 2004. This is because we do so much custom stuff that the current engine has some "holes" in it, much like you are pointing out now.
Please post the link id you reviewed and I will search the database.
Thanks!
