so in short - not harmful in the format it is being displayed in.
I appreciate what you are saying, and you are right of course - someone
could insert malicious information if they were that way motivated. The image in question on that thread had no malicious data on it though (and I know, because I checked the meta data and also the HTML code in which it is embedded).
The truth is, some guys one here have a hard enough time figuring out how to login and post anything (im looking at you Red98
) so rathen than explain anything technical with regards to the interwebz, its best to use small words and just say everything will be OK
The site which had been marked as malicious (memegenerator) has since been moved into the clear list, so that warning does not come up for the very same image now.
Thanks for the heads up though, we will as ever continue to check out these reports as they come in
