This thread was created when I stumbled this
post, first I think his post is normal and doesn't have anything suspicious since there's nothing different in my eyes e.g. font size, font color, links etc. I wanted to reply his post, so I have to quote his post, then I see there's a hidden hyperlink on his post. A normal link or hyperlink will shown with pastel blue color, but since he's using black color on his link, no one will noticed it except we quoting his post or hovering our pointer to each words of his post. That's hidden hyperlink isn't harm anyone, but I'm thinking in the future there will be scammer might using this method to scam anyone.
Since we can change our font color with any color, then I tested out to change the font color with the bitcointalk's background. It worked!
Apocollapse <- A word colored with forum's background color (#ecedf3)
[color=#ecedf3]Apocollapse[/color]
My next experiment is using forum's background color and hyperlink.
Apocollapse <- A word colored with forum's background color and hyperlink
[url=https://bitcointalk.org][color=#ecedf3]Apocollapse[/color][/url]
In this version, you can still see a difference when you're hovering your pointer to the exact word, there's a black underline.
Now what if I'm combining the forum's background color, hyperlink and underline?
Apocollapse <- A word colored with forum's background color, hyperlink, and underline.
[url=https://bitcointalk.org][color=#ecedf3][u]Apocollapse[/u][/color][/url]
In this version, if you didn't really pay attention you wouldn't noticed there's a hidden hyperlink since there's no black underline show up even you've hovering your pointer. This because if you change the font color, both of underline and strikethrough color will follow the exact font color too, it looks invisible.
ApocollapseApocollapseIf you're using PC to open this forum, you can still see the link show up on bottom left corner, however if you're using phone you can't (but you can press and hold to see the link). Dragging the whole post or quote is the only way to see the hidden words and hyperlinks.
This trick can be worse if someone use it on the blank spot between each paragraph/sentence, anyone wouldn't notice since it looks like a normal text, below is the example:

The main reason why I proposed this because I've seen so many people trapped into phishing sites, mostly the victim is a newbie, but a few old user can still tricked too. I did google and found some old threads of Bitcointalk's forum phishing before:
1.
[BEWARE!] Bitcointalk Credential Phishing Attack -- Targeting Collectibles 2.
⚠️ BITCOIN-TALK FORUM PHISHING WEBSITE! BE AWARE!! ⚠️I have visited another crypto forum built with SMF and all of the links posted have grey underline color, I guess this forum is possible to add this feature isn't? This what it looks after adding grey underline in every links:
Though you're using forum's background colors (#ecedf3 color for odd number post #1,#3,#5 etc and #f6f6f6 color for even number post #2,#4,#6 etc) anyone can still see a grey underline.
