If you've not read it yet I encourage you to read the first post in this thread, it explains a lot:
Signature Ban Appeal Q&A: read before appealing your sigbanAs I wrote earlier, I have the impression that your software is taking very old posts into account. Of course, it's wrong that I've written low-quality posts in the past, but as you've said more than once, what you're doing is supposed to improve the quality of posts. However, if the quality is already improved, so Im not sure if penalty is needed..
In your case I was looking at posts from the beginning of August (this year) until now. I'm not quite certain what you mean by "already improved" because your current posts in large don't seem to be contributing much to any given discussion, and you're often posting about the same subjects, adding superficial value in terms of advancing the conversation:
Casinos offer these bonuses and promotions for a reason, right? Surely you wouldn't deny that they're there to attract players?
If a casino offers bonuses, they should have a realistic chance of being withdraw. However, if withdrawal is unrealistic, it's better to play at a social casino rather than with real money.
To answer your question, no – casinos aren't there to generate income, but they're also not there to only lose.
To be fair, some of the threads you participate in are already low grade to begin with, and most accounts that make a career of repeatedly posting in such threads should probably be sigbanned as well.
Frankly, I don't find your participation on this forum to be genuine, nor do I think many people actually read or care about your posts. I'm not inclined to reverse the ban without some kind of additional perspective I may be missing.
