When comes online people watch and monitor your activities in and out in order to avoid being harm if your causing harm all day to others.. It may depend on things you do toward others that everyone knew is strange or unpleasant..
I have been experiencing such things here any time I see peoples searching only my post and topics when they were online.... I don't understand why maybe they want to know more about me or something else that can't be mention. only Fkn arsehole does it.
