This question already has an answer here:
Sorry for the wrong way of title used before.
All sub domains of stackexchange.com have a restriction of "minimum reputations required" for Chat Comment and Image uploading. When members have non-sufficient reputation,
- In case of image, if my question does need an image to upload to ask the question specific to topic, and if it is happened to be my first question, or my nth question with below required reputation, I cannot get specific or perfect answers. Images especially of errors, warnings or snapshots of how does the application currently look like(if it is not be explained in words) are prominent among who face those errors before. So by uploading the image they can answer the specific answer. I find no logic in relating reputations with uploading images to ask an efficient question. It will make the new member of this community helpless.
- In case of comment, some questions or answers need to be clarified slightly different than the questions or answers provided. In this case members with below than required reputations cannot ask a new question just to get small missing information from another answers. In most of the cases the questions asked slightly different than the existing questions will also be considered as duplicate by the forum moderators and members with high reputation. This will lead the member to loose the small reputation that he had before. By opening comment capability to all members irrespective of reputation will enable answerers to update the answer with more information and prevent duplication of questions.
- When it comes to chat, some domains such as stack overflow restricted a reputation of 50!!. When there is no facility to send personal messages to the members of community, to contact the member for getting additional information about the comment or answer they have posted or to make them know that someone is trying to reach them, is only possible by leaving a msg through chat. for eg: In this post the member GrIsHu has commented to check out the answer provided by him. But there is neither answer posted not link have provided. Now I cannot comment(because of non-sufficient reputation), and I cannot leave a chat msg too(and its a dream to get 50 reputation immediately so that I can enter chat) finally I have no way to ask him the link of the answer he has posted. Even using chat we can get instant help without asking new question.
When members with very high reputation(>50K) use comment to offend each other(In many posts posted on sub domains of stack exchange that I don't like to disclose), new members with <50 reputation who are in hurry or in need of immediate help can't get simple clarifications on answers with high up votes or the required answer in time.
I personally not getting the logic behind restricting newbies to upload an image, use comment for either for clarification or suggestion and restriction on chat to get instant help or use as a means of contacting a particular member.
What is the genuine reason behind these restrictions?
