Hello Mika L.
Yes, I know what you mean.
Actually, the reason why it is a sex banner is the same reason as for everywhere else where there is a sex banner. Nobody wants them and I don't like it either, but they bring more monay than others. You needn't watch their awful content. You can click and once the page is displayed, you can close it after 2 seconds or so.
Also, when I selected other types of advertissements, curiously the banner didn't work. This banner company seems quite capricious. I'm happy that I finally got it to work.
I hope you are not dissatissfied with my answer. The banner is just here to put money in the prizepool.
I'm sorry for its nature.
If you still do not agree, then let me know. I'll take your opinion into account.
Thank you very much for telling us what you thought.
I'm very happy with your participation.
have a good day and lots of lucky poker =)
