I have heard from many different people that being in dm/telegram groups are very bad for your account, I also hear from a lot of people being in them is good if they are notch related and have lots of accounts that are big accounts.
I wanted to find the real answer are they still good to use in 2020 or bad for your account now.
If you are in the same niche, following each other and leaving detailed comments (not just emojis) it’s completely fine and you should be on the safe side. It’s like having a big circle of friends supporting each other.
When you get 50-100 likes + comments during the first hour after you posted it’s giving your account a nice boost.
In my opinion 1 good comment + reply is a lot more worth than 10 or even 100 likes as it’s not easy and common to automate them in such a way a real and engaged community does.
