At one point, for a very brief moment we had this warning message in some of the memo transfers, probably based on the rep of the person sending. This gave users the possibility to click the memo messages open, but they were normally hidden from people with rep 25 and below.
This could be one option to give people the option to see the messages, but generally hide them.
For the low reps yes I think it is good but, I would still prefer not to get memos from resteem services and the like at all. Even the ones from new witnesses annoy me. If they want my vote, earn it on the platform.
"I've invested a lot on this platform, vote me for witness. Today I spent 5 SBD for marketing myself! And that's a lot!"
you got my vote.
