I seldom engage these kind of posts, but I feel I must in this instance. @jadams2k18 , memos are not a good look, and are not a great strategy. To surmise that people are not bothered by them just because they are not vocal is the wrong conclusion.

You assumed in your opening that everyone came here to make money. I have steemed for 3 years, it wasn't the reason I started, and I stay for the interaction with intelligent people with great content, a great example of which is @tygertyger.
I seek out great writers from Venezuela, the posts are of interest to me and I know the votes are precious at this time due to the crisis, but those associated with message spamming come across as someone to be weary of.
It is tempting to try these things. crypto.piotr seems to need to defend his tactics and marketing strategies time and again, with backhanded apologies that generate him more attention, associated with "helping a friend."
Keep writing, engage on posts. When people comment on my post, I pop across and check out there posts. It takes time, but you will establish more genuine following. I believe "in the long run," which crypto.piotr is very open to admit is his own plan with the memo marketing, you will build, may build a loyal following. Or if you are really luck make one or two real friends... That is priceless.
Your writing and creativity is enough. It can be frustrating to not be seen, we have all experienced that.
Many people dislike the memo strategy, we are cautioned regarding scammers.
The messages with almost zero incentive to click are not new or innovative, just as the conversation involving your charitable friends engagement technique is not a new one.
PS for the record, if anyone would avoid squashing a roach, and probably feed it and put it outside in a safe spot I think it would be @tygertyger .
