uBlock is the least of yor problems.<p>There are the individual, commercial, and private blocks and hosts files which have been created and which have to be individually cleared. Possibly IP blocks as well. As with &quot;inheriting&quot; a former spammer&#x27;s domains or IP space for email, that damage is long-lived.<p>Securing a new or alternate donain would be a good investment.<p>While there may be some tech and projects worth continuing, the brand is blighted property.
