Why Mac is scum, a concise case:
1. Tunnels in on a single post, repeating questions and completely disregarding any explanations in responses. When it's said by other players that it's irrelevant, he doubles down and even calls someone scummy when they disagree.
2. Instead of arguing that he isn't tunneling, he instead gets angry and says that he's "playing mafia as it's supposed to be played." He doesn't actually respond, instead he acts insulted that anyone questions his actions at all.
3. When an attempt is made to clear the air and explain why I'm frustrated on a personal level, he disregards it completely. This shows to me that he is arguing from a position of bad faith and legitimately doesn't care about my personal concerns.
4. He brings up statistics and tries to use them to disregard reads from people. When asked about actual mathematic concerns over his numbers, he ignores the questions completely. This shows that he doesn't care if the numbers are misleading or not.
5. With the statistics, he tries to paint the TvS chances (roughly 50% with very rough estimates with proper figures) as being 50% chance that I'm scum, not that either of us could be scum. It goes from being "TvT is less possible and here's why" to "TvT is less possible and here's why Lore is scum."
6. He consistently leaves out details and downplays my personal concerns with his playstyle instead of actually engaging in a conversation about it.
7. His "ISO" of me was based entirely around my interactions with him, showing his intent to continue Tunneling. He also tries to argue that his ISO shows that I'm "faking contribution" despite my posts and content outside of my interactions with him.
8. His ISO also tries to present him as someone who hasn't been hyper focusing me, instead pointing to his scattered posts that throw random questions at people. He also ignores how half of those posts involve him asking people about me. His ISO is meant to give a false impression of his own play so far.
Dude is Scum, imo. Scum players tend to shrug off personal concerns about their playstyle, instead using those concerns as more ammo. Soup did this, as have many others. They tend to see sportsmanship as an idea to be ignored, in the name of winning.
The sportsmanship bit isn't the only reason I find him to be Scum, though. It's all the stuff above as well.
