Most of the updates since 2016 were not well accepted by the people. It was a simple app in the start g people loved it, overtime devs made it unnecessarily complicated & that too with bad features. Some features were never fixed, most important of which was blocking anonymous people. Plus if someone has blocked you, you'll still get their shout-outs. I would say the blame falls on the dev team mainly...
So, I’ve seen a lot of my class fellows who are really good to each other on faces, but when it comes to their absence they are backbiting about them? What are your suggestions regarding such people. How should we treat them?
Guide them once or twice, discreetly & respectfully but if they are not willing to change their way, you must distance yourself from them. Such people are not loyal to anyone, they will backbite about you too once you are not around. Plus, if you stay around such people, you too will start doing the same thing.
Go to a cliff & tell him that if he loves you, he'll jump & die with you. Then if he jumps, he was sincere, if he doesn't, he wasn't so give him a nudge & make him fly.
