Thực ra không phải diễn đàn mình mới có cái đó mà thực ra vấn đề này chổ nào cũng tồn tại hết
Một số diễn đàn hóa học nó còn đưa ra những nguyên tắc cụ thể như sau, tui ghi ra đây để anh em thao khảo chơi

Red Violations: A few violations will result in a ban

1.) Please have your subject-title relating to the question you need help with. Ideally topics should be in the form of a question. Having a topic called "help me", "help me please", "chem question" is not constructive for future board members to see the topics we've already covered.
2 main reasons for this are...
a.) Future users can do a search of the forum and find what they are looking for easier.
b.) For various search engine optimizations reasons.

2.) Please don't list 5-6 homework questions and say you need help right away. It is your own responsibility to start your homework early. If you do have a lot of questions put them in one post but don't expect them to all be answered at once. Violators will have their multiple posts deleted and might be banned.

3.) In addition to rule 2, questions should only be posted once and only in the appropriate forum. Cross-posting in multiple forums just confuses the discussion of the topic and adds unnecessary clutter. If the moderators find a post that fits more appropriately in another forum, they will move it to the appropriate board. Violators will have redundant posts deleted and repeated offenses may result in a ban.

4.) Please show that you've at least attempted the problem. We don't mind helping you solve problems but we are ethically opposed to doing homework for you. Violators will have their topic deleted or locked.

5.) If you are new to chatting on the internet you should become familiar with Netetiquette. Even if you are an old hand at this internet thing you should review Netiquette 101. Netiquette 101 can be found here: http://www.onlinenetiquette.com/courtesy1.html
some examples of bad netiquette are using CAPS for anything, not spell checking your posts before posting and the use of "U" and "r" for "You" and "are". Violators will have their topic deleted or locked.

Yellow Violations: These are more forgivable, but will result in continued reminders to read this topic.

6.) Saying something like, "I don't get kinetics can you explain it to me?", or "My teacher sucks can you explain quantum mechanics?" will get you no responses on this forum. It's not that we don't want to help you; it’s that your question is too broad. You need to have very concise questions about kinetics or quantum mechanics in order for us to help you.

7.) Please do a Search before posting a new topic. There is no need to take double the space on our servers hosting a topic that has already been discussed previously.
