Isn't it possible to automate a simple message stateing "some of your recordings were reduced because of banned techniques, the banned techniques are listed at(posted 9450 days ago)please follow them." you wouldn't even need to tell them which ones (that's where their responsibility comes in to look and find out which scores are missing.) Remember the autofire was not stated clearly before, and the rules are very difficult to find on the MARP site, i doubt if 1 of 2 marpers have read angry's banned technique page....
Just gather the email addresses of those games that you ban and do a mass mailing to say one or some of your recordings were altered. This is not a courtesy, it's just to remind those that have done wrong that they HAVE and to not do it again or do it the right way next time.
