Threadstalker 

Someone who follows another from thread to thread...usually with the intent to harm them by defaming their character, putting them down, continuing an on-going argument from a previous thread of several years past...etc.

hey, remember me...remember that time you said I didn't know what I was talking about? Yeah, you...you started it you Threadstalker ....you dissed me last month....so I am going to follow you and make your life miserable tell the end of your days. Or at least as long as it takes you to get a different on-line user name...And then I'll still recognize your sorry ass...and hound it.....

Thread Stalker

A person who goes from thread to thread on a message board oblivious to other posters, addressing every post you write and rehashing old gripes based on a personal issue they have with you.

John: I am glad someone created a topic about rude drivers. I hate it when people cut me off on the freeway!

Jane: Oh there you go again John! Just like I told you before, you never have kind words for anyone. I noticed you have a problem with people ever since your thread about your sassy, freeloading cousin. You need to get therapy if you can't handle rude drivers and family members, etc. etc.....

John: Jane, you go into every thread I am in and derail it with your personal issue with me. You're nothing but a thread stalker! There's other posters on this message board, you know.
