I have to agree that what he is doing by accepting members and then asking them to have neutral removed doesn't make much sense to me
That part does not make much sense to anybody. The only thing I can think of is it being something related to Royse777 using it in future to have another attempt at having their own feedback revised.
The common sense approach would be to simply ask applicants that were on the verge of being selected for campaigns but refused because of negative or neutral tags to simply try to have the them removed then re-apply to join campaigns.
Apart from having ulterior motives for selecting participants then asking/forcing them to ask members to remove tags as a prerequisite to stay within the campaign, nothing else comes to mind and this is yet another error of judgement in a long line of errors by Royse777.
