A great many family members have started a family tree on Ancestry. One thing you have to do with hints is view the supporting documentation/sources. If you just pull in info from member trees you may get wrong information and make a mess of your tree and information. I know because I’ve done it. When evaluating member trees in hints. Always before inporting the information check out the sources. I am not saying to always ignore the information. If may give you a “hint” to dig a little deeper. Also don’t just add a source without verifing the information in the source. Ancestry supplies hint based on “best available” information. I would say maybe 80% is accurate. But there is that 20% that may be wrong. Bottom line, check the sources.
