Its getting more and more anoying. For a while it humorized me, but I realize how I drifting to upset. I know it is on me, to deal with my emotions, but at least I have to ask, is there an explanation, why this broken challenge is stil on? Is there a problem with the system?

Its for 1,5 months there now (at least) and it looks like there are more of this, (but I dont know exactly, cause I block they
grey ones normaly from my concuisness)
