Inserting some adds on a forum to upkeep it or pay the rental is okay. But inserting wild adds or hideous ones in a forum that is no longer responding to its customers, that is a bad practice. On consumer side, its paying a first time for the scenery (or the aircraft) and paying (sort of) a second time to bear this.
Mexsim's forum is not following its customers (these last weeks at least) and some people are still waiting for answers, 15 days, a month later. Aero files had also put an add on its homepage although its forum was temporily closed. This morning, this hideous add has been removed. Thank you. Billund is a really good scenery, by the way.
Simmarket has also developed a new habit : to re-launch the same product months later, which is giving it the right - no doubt - to update the official launching date. We mentionned the fact last month and it has just happened again. I cannot give the name of this product but you can check on internet what sceneries were launched on october 8. Sooner or later, if we are not watchful, we will buy the same product twice...
Mistakes happen. These people have top priority to give an answer.
