What do you do if you don't really want to keep in touch with someone but don't want to be rude?

Yea why hassle yourself right ? Its just a computer .feck it I’ll block them @Gingerbreadspice

It depends on why i guess. If they were once important to you...or you know you are to them....be honest, tell them why...and consider their feelings.
Its terribly unpleasent being on the other end of this not not knowing why.

@SW-User I’m sure it is but if they ever meant anything to me. I wouldn’t block them without some kind of indirect warning or if we were having an argument and I told them to leave me alone but they wouldn’t.

@Gingerbreadspice its seems to be the norm these days. All im saying is...even the people in yr PC and phone have feelings.
Many forget that.
I dont know your story. If you feel the only way yo get rid of them is to block and ghost them.....then thats what you must do.
