According to GMX terms, it seems that the account is deleted only after 1 year of inactivity. A period of inactivity of 6 months can only cause the deletion of saved messages and files. Or I interpreted something wrong

I understand what you meant but there's actually more to it;
This forum doesn't actually accept schedule posting, if it does, we can say that a user at his leisure could make like 20 posts and schedule them to be published later. In the scenario you painted that someone could make posts and later begin to post them one after the other, to me I may consider this as a type of spam.
Spam could also be doing things in a sequence that negates the natural way of doing things in a particular environment. In the issue in question, the time between posts is 2 to 3 mins, this could also suggest that this is a bot operation.
But in all, I don't want to belong to a forum where people are interested in quantity discussion and not the quality of the discussion.

Since some users have suggested to you what to do i think you might want to lock the thread up since there is no point keeping it open anymore. Just do as Charles-Tim have advised, report the post to moderators and the post will get deleted, spamming is not encouraged here and by reporting the user and his post you have made a good contribution to the community to help keep the community clean and conducive.

If people can’t learn to read rules and regulations easily then learning the hard way is the only way to get them to learn.

Here they do it knowing full well the next step. They know what their next test result will be and they systemize it as per their results. This is because participants are required to have an account on their platform so that they will systematize the systems themselves.

Whatever they do and how they give gifts will keep them within their control. So that they can use it next time.

I will, but I just wanted to bring this into everyone's notice, or maybe find a quicker solution to the problem.



That's part of the problem, I wouldn't be concerned or have any problems if he was making quality posts, I enjoy reading posts that don't waste my time, but that isn't the case here. All, or most, of his posts are generic low-quality posts which makes is clear how he is able to write a post every two minutes.

Rule or no rule spammers will still spam, and plagiarists will still plagiarise, and that's just fact. The forum rules don't support spamming and creation of generic shit posts but still every now and then we find shit posts and plagiarised contents and write ups scattered around different boards on the forum. Personally I'll say that no one including Moderators are to blame except the spammers and plagiarists themselves.
Numerous times I have across posts like this with complaints of some users constantly spamming and creating generic posts. However I'll say complaining and creating threads won't solve a thing rather the best thing to do is assists moderators to clean the forum.
Like other members here have previously mentioned ,all we have to do is report posts like these to help moderators spot them.

I can't say for others, but I personally support your merit-source application. And my reason for that is that you always helped me in one way or another. From answering my questions to clearing confusions and so on. You have friendly behavior without any question. I have been noticing that since my newbie days. One trick (I won't say trick, but...) I learned from you is making quotes smaller. You always do that in your posts.

That's the whole point here. The hosts know and probably have experimented and observed which kind of giveaways are more beneficial for them and their business, hence they are hosting giveaways that are generating better results for them as a whole. If they are not hosting giveaways that would pay winners directly to their wallets but ask participants to have an account on their platform, it means they have found this to be more productive which is why they are choosing this way of doing their giveaways.

Usually users tend to do like this because they have paying campaign. Report it to the campaign manager so the user will get removed and get nothing, which i think he is really in a campaign or just wearing it.

As for forum rules, there's no rules for "burst-posting", unless the posts are considered and reported as spam. But if the posts are somewhat good, then there's no issue at all.

If posts are spam, let's report them and the spammer will come to a ban soon.

A little bit beyond this case, you can see a user makes a series of post but if these posts are good in quality, it's not a spammer and no issue at all. Assume he composes these posts and when are ready, he releases it in a series. This style is not common but I would like to give the example to show that quality is key of deciding a post is spam or not spam, should be deleted or kept and a poster should be banned or not.
