Of course not. This is not the goal of twiends. The guideline we put in place is that you follow someone for at least a week to see if you like what they tweet about. If you find them offensive or spammy then you can of course unfollow them immediately. Over time you can decide who you want to be long-term friends with. We want our introductions to mean something, and we want you to honestly check out your new friends before unfollowing them.
