Zimon logged into his main account using the same IP as one of the alts 40 minutes after the fact. His main accounts last activity on that day was 1:36AM UTC, the last of the spam reviews was posted at 12:58AM UTC.
It's a residential IP, and the cross over between accounts is less than an hour.
We can only promote a thread when we are notified about it. If he updates the thread and then doesn't report the OP, we don't know about the update, and so it doesn't get promoted.
Unfortunately devs using alts to post fake reviews is actually quite a common occurrence. As long as the developer owns up to the "mistake" and promises to not do it again then we're fine with giving them a second chance and not posting a public message. However, it's clear that in this instance, from the messages posted on Discord, that there was zero remorse plus a denial of wrongdoing, so we no longer felt comfortable giving him the benefit of the doubt, and enforced our rules more stringently.
This is the first time I've had any interaction with him, and I haven't even played this game. Do you seriously think I randomly go around targeting innocent developers just for kicks? In the past 5 years we have banned reviews on 3 games including this one. This is an incredibly rare occurrence and an action we do not take lightly.
