From time to time GOG make a mistake and then correct it. It's very likely Ciemnogrodzianin caught it when it was listed and posted here while GOG had already made the correction. ¯\_(ツ)_/¯

Exactly. And, please, note how it works during a big sale:
1. I usually start my script shortly after a sale starts.
2. After 5-10 minutes I've got all the data.
3. I start publishing lists, but posting is limited – I need to cut the list and I cannot post more often than once a 10 minutes.

For big sale it means that I need several hours of posting; when I cannot make it asap (every 10 minutes), it sometimes it takes me even 1 day to post all the data (that's this Winter Sale case). In consequence sometimes the deals posted at the end are already corrected (this specific case). My rule is to post every offer as it was released and then start checking any changes.

PS. I cannot see any simple solution for the problem. Perhaps I could simply share a full list elsewhere, outside the GOG forum, for those who want to scan the list asap. As a list is ready a few minutes after a sale's launch, it is possible. Let me know if you have any ideas how/where to do that.

The problem is actually quite simple to solve once you understand what the problem actually is.

The problem results from two properties of the forum software:

1) Posts have a maximum size.
2) When a user posts twice in succession within a short amount of time (10 minutes) the forum doesn't create a second post. Instead it edits the first post and appends the content of the second post to it.

When you post twice within 10 minutes 2) will happen but since your lists are close to the max size already 2) will fail because of 1).

There are two solutions:

The first is obviously to wait 10 minutes between posts so that the forum will create a new post.

The other one is just as obvious: Don't post twice in succession. Or in other words: Create a second account for posting your list and when posting the list alternate between the two accounts. Account A will post part 1, account B will post part 2, A will post part 3, B will post part 4, and so on. That way you can post everything without waiting.

Oh, thanks, however I'm quite aware how it works. Long time ago I saw how people make exactly the last solution, but I'm a One Person Army ;) and I also simply don't want to switch between accounts myself. I'm just keeping my PC open and post from time to time, trying to be as close to 10-minutes interval as possible. 99% of year it's fine; the problem is only during big sales and only in their day one. I think we can simply live with that ;)

Oh, I've asked GOG to give me a special permission to post without time limit :D, but – guess what – it's impossible. The same as almost everything here (fixing old bugs, removing misleading "GOG Connect" link, fixing purple dot bug, well, everything is impossible for today's GOG).

The forum software is so old that it is essentially one big Jenga tower. ;-)

But if you know your way around programming (which I guess you do since you wrote scripts to automate the sale crawling) you could easily automate the posting.

I've considered this one. Especially that I've already used the tool to exchange some data with users here. Some problem may be that there's also some formatting in here and hiperlinks. The raw list is less useful, I suppose.

Scraping and parsing is much easier than interacting with web page, especially when you consider how specific is the forum interface (with pop-up window for responses etc.). I've considered that, but never decided to make the effort.

I was assuming that the pop-up does nothing but a simple post but it seems it uses javascript to post the form which is downloaded in minified files so it isn't that easy to understand and replicate.

But at the end of the day you could always remote control a browser via code. That has been made possible to automate tests.

Look up Selenium Webdriver/ChromeDriver if you are using a Chromium based browser or Marionette for Firefox.

Maybe use something like GitHub or GitLab, since they support markdown formatting and also don't require accounts for people to see?

This! Sounds like the easiest solution and addresses all the needs. Thank you!

Yup, I'm aware Selenium is there, but usually it caused some various problems for me, so I avoid using it. Perhaps I should reconsider this approach. One-time effort to develop may be easier than constant effort to publish all the lists. Thanks.
