I’m not always on-line as I'm on the road for much of the year, but if there is something on Thorn Tree you feel requires the attention of a moderator e.g a spammer, then you can report a post by clicking on the flag icon, found in the top right corner of every post, provided you're logged in. Once you do that, a moderator will look at your report in due course.
There is no point reporting the same poster multiple times. One report is all you need, but if you feel the poster concerned has many posts requiring attention you can add a brief note in the comments area of your report. Clicking the flag icon repeatedly only increases the time taken to process your reports...
Our moderators work from different time zones so please be patient.
