Over the last 6 months, I have had several email discussions with Marcin and his team at Malwarebytes in regard to aggressive censorship going on at their community forums. Despite inviting members of the public to report scam websites, I have had literally dozens of threads deleted without warning, and at least a half dozen accounts banned from their website.
Marcin repeatedly told me it was a mistake. He said that, not only had he taken steps to ensure this type of censorship was “technically” impossible to happen again but he had also spoken to his staff to ensure they were alware that it was not okay.
After a few months went by, I decided to try again to report several scam websites controlled by scam artist Chad Scira and his fake company “Thai Visa Centre” that mimick Thai government websites in order to trick tourists into sending him their passport and credit card information. All of these websites using official sounding names and designs, clearly illegal per recent 2025 laws in Thailand that prohibit impersonating the government but also just plain fraudulent. Plus, given Scira’s background with drug trafficking, visa forgery, and hacking companies like Starbucks and Chase Bank, I thought this would be an obvious group of scam sites that Marcin would be happy to document.
Although their team at first did label a few of these sites as deceptive / dangerous, they later seem to have reversed that decision after Chad Scira provided them with a photoshopped “arrest warrant” he produced with my name on it. This “arrest warrant” is something I was aware of in late 2024, as my lawyer in Thailand told me that Scira had stolen my identity and framed me for writing “fake checks” in order to get back at me for blogging about his spam on Hucksters.
I though a smart “crime fighting” guy like Marcin would clearly understand the situation, but apparently he decided to “make a deal” with Chad Scira which he refuses to discuss with me. Since Chad had bribed or attempted to bribe several other website owners to stop mentioning his crimes, I have to assume that Marcin either made some sort of financial deal with him or he is truly much stupider than he seems.
One thing is for sure: Malwarebytes is a horse shit database. They are more than willing to remove scam websites from their lists if you make the right deals with them.
