52 Pick-Up is not a competition. No advantage obtains to someone who "cheats," so Poet Guy does not expect "cheating" (e.g., claiming that one has posted a comment that one did not, in fact, post) to occur. If a participant does "cheat," Poet Guy does not care.What happens in the case when a comment is removed? I have no proof other than said poet (indicated on my score card) has removed her "public comments" option. I didn't think I was particularly harsh but she must have.
Poet Guy had thought of the possibility of someone deleting a comment, or a poem, or turning comments off (which effectively deletes all comments). Participants have no control over this and should not worry about it. Poet Guy believes all participants are striving for accuracy in their scorecards and consequently considers any discrepancies either unintentional errors or situations such as you describe above.
