When I am busier than usual I will just delete posts with long paras of densely written material and or with links I do not recognise. I do not have time to word count or count multiple postings. It is quicker just to approve them if I can see immediately they do not make potentially false allegations about named people or institutions. I do not censor views from other political perspectives and allow plenty of criticisms of government. I do give myself the same protection as anyone else from personal abuse and the worst false allegations.
