My goal is to try to do something practical just on data compression. I have neither knowledge nor experience about malicious software mentioned. You may be comfortable about this.

I was referring to the practice of downloading executables from such forums in general, not to your post specifically. I have no reason to suspect that this particular post contains any malware. But in most parts of the software world, Open Source has been the standard for experimental publications for a long, long time, and seeing a forum depart so strongly from that standard is certainly surprising, and does of course have security implications when this practice is used at scale.
You can always use a sandbox if that's the most concern. A bigger issue is that, as like other established forums, enough many people don't know much about data compression and contribute to the noise.
