10 or 20? Please remember that the threshold for the normal appeals process, which can involve up the following in extra work: WG Chairs, AD, IESG, IAB and ISOC Board is 1 person, who doesn't even have to be an active participant. Has the IETF been drowned by frivolous appeals? No. Am I worried about a rush of frivolous recall petitions with SM's proposed change? No. Consider that for remote participants, contacting 9 other people and persuading them to sign a recall petition is a non-trivial task, comparable in difficulty to walking around at an IETF meeting and finding 19 such people.
