Social Media with Proxies?!?!?

Hopefully im posting this in the right forum, but how do proxies play into social media?

Say i set up 5 pintrest accounts on 5 dedicated proxies. Then blast the shit out of them on GSA, and eventually the 5 proxies get blacklisted.
Can i turn around and put the pintrest accounts on 5 different accounts with no problem? Or will the blacklisted IPs get the social media accounts banned?

Thanks

Anyone have any ideas or insight?

It really depends on the company. Some of them might blacklist IPs, some of them might blacklist accounts, some of them use external services to check the "quality" of your IPs (so that they know if an IP spams some other platform). For Pinterest I've been able to create multiple new accounts after some accounts were banned with that IP.
