How much will someone need an SDK set for all popular sites and instant messengers (for mailing lists and other things)?

Question

Marketing

Back in 2015, I slowly started writing bots - programs for automating mailings, parsing, posting and any other manipulations on various sites, social networks, and so on.
The API of many sites does not provide all the features or is not available at all, so this software acts differently - it imitates user actions.
Technically, I always build this around HTTP/S requests, and never use browser engines like selenium or phantom.js.
Therefore, the tactic has disadvantages (bots stop working sooner or later), but there are also advantages - mailing speed, light weight, writing and debugging speed. And they do not always stop working so quickly - they can take several months, but I have seen samples that have been living for several years.
I constantly improve tactics - I increase the accuracy (now I am working on higher SSL accuracy), I create utilities for automatically writing such bots.
But apart from freelance orders (not so frequent), it brings me nothing.
Therefore, since the same 2015, I have been dreaming of the idea - using my utilities in a short time (so that it does not have time to go out) to write an SDK / DLL for many sites, as well as instant messengers and mobile applications, so that other programmers (even very beginners) just take my SDK / DLL (capable of performing all the basic tasks that a user performs on this site) and built a smart bot in almost a matter of minutes.
These can be bots for PR, parsing (the same VK and Avito), for automating routines on some services in their work, etc.
At first I plan to sell licenses for a small amount (from several hundred rubles for each site).
And if it doesn’t work, then put it on Github.
There will also be related things such as proxies, accounts, ready-made SDK / DLL for captcha recognition services.
And spread it all.
In 2016-2017, I put these ideas aside in favor of more "understandable" projects for the community, for which they also paid money, but they abandoned everything, and I was left with nothing. Therefore, I began to think again about this option - in any case, I like it and it is not very laborious compared to other projects.

Answer 1

Are you trying to ask if someone needs a toaster spam tool?

Answer 2

It is necessary of course, but I think you will get tired of supporting it.

Answer 3

It is necessary, of course, but you can’t take it impudently here.
First, support. Those. here you need not one person, but a whole team to keep such a mountain of everything in working condition and fix bugs.
Second, user support.
Third, marketing.
Fourth, usability.
In short, from afar the topic is interesting and cool, but there is such a mountain near the crap. After all, if something is not on the market, maybe it's not just like that :)
But if anything, go for it! If you make it cool, I'll use it myself.

Answer 4

it mimics user actions.
Technically, I always build this around HTTP/S requests, and never use browser engines like selenium or phantom.js.

The imitation is only partial, because the user not only submits, but also moves the mouse.
