Kind regards. Symantec.cloud support staff can certainly get the IP cleared, but as long as spam is still seen to be coming from it, then it will get re-throttled again.

What I would recommend is getting a case logged with Symantec.cloud support (please bare in mind that for security purposes they will only log tickets for authorised contacts of clients - so you may need to ask an intended recipient who uses the Symantec.cloud scanning service to log this on your behalf initially) but what the support staff can subsequently do is put a watch on the IP and look to analyse more carefully the kind of traffic that is causing your IP(s) to get constantly listed, at least that way they can feed back that information to you so that you can investigate more accurately on your side in case of a repeat offender.
