Guys this thread can be closed, ignore all the old GMs posts in old forums they dont represent current CCPs stance about this issue as you can read on this post (edit):

Removed discussion with a GM. PLease follow rule 2. Thank you. -ISD Dorrim Barstorlode
Enjoy and lets play EVE 
EDIT: Ok apparently, I cant copy paste direct conversations that I had with senior GMs about this, so heres the TLDR:
"Its OK, within current CCP stance to continuously gank, scam, spy, bump, threat, steal, pirate, extort and attack the the same player or any other player for as many times as you want, INCLUDING following him around, because the opportunity to do so is built in the game mechanics!"
@isd let me know how can I rephrase this in order to let others in this thread know about it without breaking forum rules if this edit isnt enough thanks.
