I've done it since I was young, but am a little more thorough now. I feel like something shouldn't be in my life anymore and completely or nearly completely remove it. Most of the time I never go back to whatever it was I got rid of. dA is a weird exception. I'll think my art is okay to have on the internet, then I find no point in it and remove it. If you've seen that I've recently rewatched you, it's because of that. I went to delete my dA account, so I removed favorites and watches. Stopped. Then, gave myself a few weeks/months to see if I wanted to keep it. Decided to keep it, even though I feel my art isn't worth being seen.
Anyways, sorry for rambling. Have a lovely week.
