The lead put a comment about SCAM- this was a complete lie// there were many replies [not very favourable ] to the lead so he closed the post -the day after he reopened the post and made very nasty comments then closed the post again, by doing this no-one could comment The lead is clearly violating not one but severel rules.This is not the 1st time he has done this but as he is the only lead[others have requested to be joint lead but all have been denied User's recommendation: that you appoint another lead.
