I have just seen on the MSE that some peoples are working in a group for just increasing their profile reputation.
For example like person-1 asks a question & within 20-30 minutes person-2 gives his/her answer on that question & person-1 do upvote & accepts the answer of person-2. We can't get it in just one time but If we properly monitor then we will see that if person-1 has asked 4-5 questions on MSE then all his/hers questions are answered by person-2 & person-1 has always accepted his/hers answer.
This can be also neglected but when we see in the comments that person-2 automatically get this thought into his/her mind that the person-1 who have asked this question is using an extension or not.
We can neglect it in this sense that directly or indirectly by doing this they are providing something to the community but my question is.
Is it fair to the other members who are actually working in a fair manner for this community & sharing their knowledge here to help others?
