FACEBOOK KEEPS ON STOPPING ME FROM MAKING POSTING

I think one of the reason for the petition not having substantially more signatures on it, is that Facebook appears only allow me to make 30 postings per week, and if I exceed this amount in this sort of period it prevents me from posting or joining groups for about 5 days. I do not know why this is, and yet it puts substantially restrictions on my freedom of speech. Other petitions being promoted on Facebook do not appear to have this sort of problem, and so I assume the subject of the petition I have been promoting is for some reason being singled out and blocked by other Facebook members or Facebook's system (some members have said they advocate the exploitation or enslavement of children and think that the petition is in the words "a load of pant"!). Consequently, if you would like to, please share the petition as much as possible to get around this problem :-)
