Thank you for taking the time to respond.
1. When I press login the browser is thinking and just sents me to the index page (not even the login page), there is no message displayed or even a pop up.
As far as I know, it's supposed to take you to the index page, and there is no popup or anything like that.
You should however get some box with a red text, saying roughly:
"Sorry LuckyYOU, you are banned from posting or sending personal messages on this forum. You have been banned by a forum moderator. You may appeal here: mail address"
(above text is for permanent bans, temporary bans might have other texts.)
2. A potential ban. I understand there is sig. spamming happening here, but I consider myself nor the post spam posts. While ontopic i always try to contribute and share my knowledge.
Tend to disagree, but I am no one to judge.
