This is false
Reallocation of an IP does not clean up its
bad reputation. Moreover the one IP may be part of entire block of IPs with bad reputation. Thus, advice “You do what you want, if you get blocked it’s your fault" is inappropriate since the guy who had that dedicated IP before you may have followed that advice. A lot of ISPs but a lot of weight on domain reputation these days -- in that case it doesn't matter what IP you have, and if you have a good domain reputation "you can take it with you."
