One thing that is also a con but is part of the reality of life as a Christian anyway (i.e. there's no escaping this) is the weak Christian who posts or repeats quotes and tidbits from ministries that are run by a false teacher. We agonize over our brethren who are embroiled in the snares of the devil and who prove it by unidscerningly following them, and by repeating the lies the ministry puts out there.
A pastor named Jordan Hall wrote a heartfelt warning about this and I re-post it here. In my opinion they are good words well stated. I use most of the discernment ministries Pastor Hall mentioned, and I'd also suggest my own The End Time blog, Sharon Lareau at Chapter 3 Ministries, Erin Benziger at Do Not Be Surprised, Sunny Shell at Abandoned to Christ, and Aimee Byrd at Mortification of Spin (The Housewife Theologian), DebbieLynne Kespert at The Outspoken Tulip, and already mentioned in the essay, Amy Spreeman at The Berean Examiner.

Not too long to read: My friends, from a pastor's heart, we must be careful who we quote on Facebook and whose material we share. Please take the time, before you do either, to spend just a single minute to research the individual or ministries you're promoting by sharing their material. Before you quote or post a meme from Beth Moore, Proverbs 31 Ministries, Joyce Meyer, Joel Osteen, Andy Stanley, Steven Furtick or other popular 'Christian' leaders or organizations, please search the web with their name and the word 'discernment.' You'll find the information you need in no time flat, and you'll avoid causing your Facebook friends to stumble by introducing them to chaff and tares.
Why do that, you ask? Do that because Romans 16:17 tells us to "Mark those that cause divisions and create obstacles that are contrary to the doctrine taught [in Scripture]." That instruction is two fold (A) Mark them - that means to qualify, characterize and typify them as dangerous as a warning to others and (B) avoid them. When you post something from TD Jakes or Andy Stanley you are marking them as trustworthy. You are then exposing your friends and loved ones to their false teachings.
It is here that some say, "Well, I liked the quote. I'm not endorsing the person." Well, I get that. Really, I do. I'm sure Charles Finney or Adolf Hitler might have said something at some point I might agree with. But, we shouldn't go around quoting Hitler or Finney. Whether you like it or not, it IS an endorsement, and you might turn people onto ministries that are spiritually toxic.
Likewise, be careful when you "like" statuses that repeat the words of false teachers. I know you like the person who posted it. I know you liked their good intentions. But for the love of Jesus (literally), do not 'like' the words that proceed from the mouth of those who masquerade as shepherds but are inwardly wolves. Do not give the impression to your friend that you like it that they appreciate false teachers. Rather, you ought rather to mourn and warn them.
Here's a tip for your convenience if you think, "Good grief, am I supposed to research every pastor or ministry I post or 'like' on Facebook" (the answer is YES, by the way). As stated above, google "person/ministry's name" and "discernment." You'll find a wealth of resources from polemicists (those who specialize in errant teachings) like Chris Rosebrough, the late Ken Silva, Amy Spreeman, Michelle Lesley, Jeff Maples, Pulpit & Pen and more. Discernment is a gift of the Holy Spirit, and God has gifted people with discernment to edify and equip the church.
Finally, this is the information age. This does not require going to the library and looking up handwritten sermon manuscripts on the microfiche. A discerning Christian, through just a little bit of research (literally, just minutes) can determine wolf from lamb in short order. For the love of Jesus and his church, please be careful with what you post.
