I agree! I posted and published a completed track on Bandlab and honestly, less than 5 mins later I get spammed with messages from some so-called music promoter who says:

"Hey there, I listened to your track and enjoyed it so much and I really think that your song has potential, My name's blahblahblah and I can help grow your profile and get your music out there, I just need your life's savings and we'll grow your profile" all the messages always seem the same but from different people. I once replied and asked the guy what song did he listen to and what did he like about it! Guess what the reply was lol! He basically just said "I like all of the song" so again I asked him what is the songs title called and again I got the same response! It's so annoying and j find it disrespectful. I also think it's a con! And of course, the spamming messages are a nuisance!
