it does not matter in most cases. This information is part of the provider's profile and the first posted review establishes the profile. So even when a hobbyist enters a change, e.g. change 'smokes' from no to yes, the original information will stay anyway.  This will stay this way forever unless either the provider or a hobbyist 'reports a problem' to the TER review staff and it is accepted.  From my one experience trying to change this once, it is quite a frustrating and time consuming  process and I'm afraid many avoid doing it as a result.

If it didn't require some time and dedication to submit an approvable review; every associate of a less than ethical provider would be submitting one for their friend. The time intensive nature of the process probably helps thwart LE espionage also.
