The Celtic boss has revealed he plans to make a comeback to Twitter after the firm got in touch to ask him to return.
He closed his account, @OfficialNeil, last December.
He said: "I think I'm going to go back on Twitter.
"They've asked me to come back and I think I probably will because I did enjoy it."
The manager said the bad side of social media can be seen in the recent abuse directed at Manchester United gaffer David Moyes, who is also a former Celtic player.
Lennon said: "Like everything in life, there are good things and bad things about it.
"What I don't like, say with the criticism of David Moyes recently, is the type of criticism that comes from it, almost trying to humiliate the man.
"I find that very crass and unfortunately it seems to go with the territory these days.
"Constructive criticism you expect but the poisonous stuff, and I've had it myself, leaves a bitter taste."
As for his players, Lennon says he is happy for them to Tweet, as long as they know where to draw the line.
In an interview on the Fifa website he added: "The problem was that it started taking up too much of my time.
"But I certainly don't have a problem with the players going on and engaging in that type of thing.
"What's made very clear, though, is that there's a line they cannot cross.
"They know where that line is.
"Social media is here to stay and, as long as it doesn't detract from my players' duties to this club, I don't have a problem with it."
