I've realized that my standard spam checking isn't picking up everything. I got a backorder domain that looked 100% clean this morning, but had a malware warning the instant I got it hosted. Checked in a new GWT account and it had that warning. I probably need to go back and check 10-20 of my somewhat recent domains to be sure. What is the safest/best way to check 20 domains in GWT? Create separate google accounts for each? Is there a limit for signing up for new gmails? Thanks!
