If you’ve had your email address listed on a webpage somewhere then chances are at some point it’s been harvested by a spammer. Most people hate spam, myself included. I do prefer to call it unsolicited commercial email (UCE) but that never caught on. Because of harvesting, many sites started hiding or removing email addresses from their webpages. This never made sense to me doing so not only make it harder for spammers to get your email address but you also make it harder for the people you legitimately want to have your email address.
I’ve seen all kinds of trick from images instead of text to javascript tricks. In the end none of these things will stop spammers.
The one trick I hate the most is writing out the email address in words, like this – thechivesubmit [at] gmail [dot] com. Do you really think it will stop spammers? It won’t. Instead of writing software that parses text for the @ symbol they will just write software that parses [at] or (at) or {at} or some other goofy thing that people use. How many combinations are there really?
I have a variety of email addresses that have been published on line for more than 14 years. I definitely get spam to those addresses but the filters on Gmail do a good job of keeping the spam at bay.
If you want people to email you then make it easier for them to do so, not harder.
