I don’t think you can simply say something tantamount to “I think you’re an evil person btw pls don’t reply” then act the victim because they replied.

If they replied a single time, sure. Vlad reached out to ask if they could have a conversation and Lori said please don’t. Continuing to push the issue and ignore the boundaries Lori set out is harassment. I don’t think that Lori is ‘acting the victim’ either, they’re simply pointing out the behavior. Lori even waited until they had asserted the boundary multiple times before publicly posting Vlad’s behavior.

If the CEO had been sending multiple e-mails

How many do you expect? Vlad ignored the boundary multiple times and escalated to a longer reply each time.
