What do you do with unknown texts?

[Pookie Bear]

I get a lot of blank text messages from people in my Contacts - mainly because my name begins with A - and I never do anything with them. Occasionally, however, I'll get texts from unknown numbers (usually more than one at a time).

Does anyone else experience the same thing? If so, do you text them back, or do you just assume it might be some naughty scam and ignore them?

Just curious and figured this didn't qualify as a discussion about phones, so put it in here.....
