Yes it is!
If done right the text enterd is safe and you dont loose any of the data. doing the other way lots of data can be lost and the code could be bybassed.
Updated: I just had to build a code to remove the text in tye's post. This is what I came up with $value =~ s/<(([^ >]|\n|\s\/|\s\S\S)*)>/ /gso;
Ya that code kinda works better but it still removes parts that it should not and like tye stated "Escaping" is the better way to go.
