I do have several very good IRL friends who I know for more than 30 years and who are members of this forum (they are those who suggested me to come here in the first place) but not even once it cross my mind to sit at their computer when I was at their place and write forum posts and vice versa.

Thing is, basically all those who were caught abusing forum rules via alt accounts claim that those are their friends or family members, and while that may sometime be the case, no one will believe them anymore as this excuse has been used so much.
