Since you mentioned my name I will answer you.
People that are friends with me, like me, they like me as a player, they can take my humorous side with a laugh and we can talk about the game since we all enjoy playing it.
You call me abusive, if I get into a table with "good" players that take arena seriously and not like a joke as many of my partners have done in the past, then I wouldn't have this "abusive" reputation. Do you know how hard it is for me to keep myself from complaining if my p starts to troll me and starts GTing when I GT ? OR when he doesn't play his card to block an opponents 1-2 and his excuse is "it did not matter". There are people that take arena as a joke, with no seriousness, these types of people make me talk at that moment. Many of the competitive arena players or game gurus as they call us wanna have a change of how arena works and the entry requirement for it to not have to deal with people like that, I am just the guy who expresses myself more publicly.
When I first started playing on BGA. I did not know back then people are SO sensitive when you tell them something. Since then I believe I have improved by a lot and don't talk bad to people. The only thing I sometimes do is ask my partners why they did that when they could have just played better. Maybe it is harsh or abusive as you say but what is the point of having a chat table if we aren't allowed to chat?
If chat is a problem I can help anyone that wants to add a CSS to their profile and they can remove chat completely.
Also BGA's system of moderating,well I will leave that to the public if its fair / unfair.
Numerous accounts I do not have. I made some "new" accounts it is true only because when I get reported in comparison with other players, instead of getting -10 karma points for a minor offense I can drop down to -45 karma points. Do you know how unfair that is for me? Imagine playing competively in arena top10 and suddently get reported for 1 word and go down to 45% karma then can't enter arena until you reach back to 75%.
People have made new accounts numerous times, I do not see what's the problem with it as long as you are not kingsmaking or abusing some sort of system.
Also there are players that have blocked me on Nazghul with only 1 game played against me and only because they heard rumors in the start when I did not really know much about the site which in my opinion is unfair, I played with them in "new" account and we had no problem whatsoever.
To mention a few, I will write them down publicly because I wish they will unblock me and we can play games together. Pako, lock, simu, astropurpurea, GrandSmurf, zeezee, Paumenn.
Also it is really ironic someone that made a "new" account came and made a forum post.
At the end of the day, tichu is just a game, I know, and lately I just move on after losing a game. I always say Gg to my opponents and Thanks for the game as sportmanship.
I will also leave something here since it is related to the person behind this post:
Imagine playing a 41 minute game, this person enters your game in the last round, hasn't watched any of it and writes in the chat this thing then comes on the forums and write about you.
Have a great day.
