LOL, I see what you did there. Thanks for the "Gift!" I guess if we got paid a little to accept all of our spam, we wouldn't care that much. Since I get these kinds of memos only a couple of times a week, I did click through to your account to see what was going on, so it worked. :)
I imagine that the whales here get a lot more of it than a little prawn like me, so maybe it is annoying for them.
If a whale doesn't want to receive dust transactions, then they should use some sort of filter software to remove the transactions so they don't see them. It should be OK for any account holder to send a memo another account holder unless if they explicitly opt-out.
It seems to be the only way to send a direct message, so I agree with you. I guess if you want to send a private message, you'd have to take it to another platform too.
