Freind of mine published a paper with fabricated results in a top journal and got accepted and i feel disgusted [d]

A friend of mine was doing gap analysis as a project , the result he got werent that big from the original papers, so he simply fabricated and increaaed the metrics results here and there, AND IT GOT ACCEPTED IN AAAI. HOW DO THEY CHECK THE PAPERS DUDE, i was in a group with another two and worked soooo hard in an optimization paper, and was sooo happy to get accpetwd in acl, but seeing and knowing that someone fabricated and got to a better conference made me soooooo mad. I wouldve expected something like aaai would check and know if a data is fabricaged somwhow, didnt expect this from a top conference like that And then this type of people qill go and do their phd in one of the top unis because if this, i wouldve expected the system to be mkre advanced and professional in the academic field, specifically for somethinf like aaai
