You should look up the rules to make sure you know them before you post.
Section 3.3 B (13) of the Competition Manual which is "deliberately seeking to manipulate ones player rating through intentional misplay or withdrawal".
I'm not defending bailing without notifying the TD but it has nothing to do with what the 888 rule is supposed to address.
Perhaps you should read up before accusing others of not reading.
Ratings Manipulation Addressed:
Although not directly related to ratings manipulation, the 888 code can also be applied to players who DNF without giving the TD sufficient notice they would not be showing up for the next round. "Sufficient notice" is defined as at least 15 minutes prior to tee off assignment time. Players who DNF without such notice will be reported as an 888 code by the TD.
