So there is verifiably a person in your area who has a beef with you.
For what I see there is at least one NEET who consistently posts from the same broad range your post was just made from. The narrow range differs. What I think this only means he has the same ISP (as I previously wrote) but not necessarily the same location, could be the other end of the continent, I can't tell. Maybe he can prove somehow he is not it.
Also it can be that the spammer doesn't post actively beyond the spamming, or the one who called you or flipped your place, or who taunt you here, might not even the one who spams the board slim chance. Again, I can't tell, the spam - like he posts these days, today as well, the questionable porn - comes from all kinds of different IPs.
When I was banning a person the other day, he consistently used the same broad range, just got different IPs, sometimes from the same narrow range. So he was just renewing his IP, resetting the router, etc.
