"hey friend. your reviews are too short and at times few words. not adding much value"

i think you are either new or non English speaker. in case if non English speaker, thing which may help you out is that you may leave reviews on ethos even in your native language. also, your review should explain with reasons shy you are reviewing someone positively. reviews which are of few words or generic often get down votes and gets profiles negative review from others as people often think of those profiles as spam. apart from this, such actions do not help with xps so even with you sponsoring gas for such reviews you may actually not get any xp points. i hope above helps. i am happy to remove my review if you agree to leave more meaningful reviews in future.
